Rename CustomSchemeContext to SerializationSchemeContext to improve
clarity and move to it's own file. Improve kdoc to make things less
confusing.

* Update API current with changed API

* CORDA-4104 Implement custom serialization scheme discovery mechanism (#6854)

* CORDA-4104 Implement CustomSerializationScheme Discovery Mechanism

Discovers a single CustomSerializationScheme implementation inside
the drivers dir using a system property.

* Started MockNetwork test

* Add driver test of Custom Serialization Scheme

* Fix detekt and minor style error

* Respond to review comments

Allow non-single arg constructors (there must be one no args
constructor), move code from SerializationEnviroment into its
own file, improve exceptions to be more user friendly.

* Fix minor bug in Scheme finding code  + improve error messages

* CORDA-4104 Improve test coverage of custom serialization scheme discovery (#6855)

* CORDA-4104 Add test of classloader scanning for CustomSerializationSchemes

* Fix Detekt

* NOTICK Clarify KDOC on SerializationSchemeContext (#6865)

* CORDA-4111 Change Component Group Serialization to use contex when the lazy map is constructed (#6856)

Currently the component group will recheck the thread local (global)
serialization context when component groups are serialized lazily.
Instead store the serialization context when the lazy map is constructed
and use that latter when doing serialization lazily.

Scan the CorDapp classloader instead of the drivers classloader.
Add properties map to CustomSerialiaztionContext (copied from SerializationContext).
Change API to let a user pass in the serialization context in TransactionBuilder.toLedgerTransaction

* Improve KDOC + fix shawdowing issue in CordaUtils

* Pass only the properties map into theTransactionBuilder.toWireTransaction

Not the entire serializationContext

* Revert change to CordaUtils

* Improve KDOC explain pitfalls of setting properties

ENT-5768 startFlowWithClientId permissions (#6708)
Do not let a user reattach to a flow started by another user.

Reattaching to a flow using startFlowWithClientId for a flow not
started by the current user throws a PermissionException

Reattaching to a flow using reattachFlowWithClientId for a flow not
started by the current user returns null.

finishedFlowsWithClientIds does not return flows started by other
users.

Normal rpc permissions around startFlowWithClientId and
startFlowDynamicWithClientId has also been added.

To allow admins to remove client ids as well as be able to see all the
client ids on the node, admin versions have been added that bypass the
user restrictions. These can be permitted via rpc to only provide
their usage to admins.

CORDA-3822 Add CordaRPCOps.reattachFlowWithClientId (#6579)
Add `CordaRPCOps.reattachFlowWithClientId` to allow clients to reattach
to an existing flow by only providing a client id. This behaviour is the
same as calling `startFlowDynamicWithClientId` for an existing
`clientId`. Where it differs is `reattachFlowWithClientId` will return
`null` if there is no flow running or finished on the node with the same
client id.

Return `null` if record deleted from race-condition

CORDA-3692 - Store result information in checkpoint results table (#6473)
Making statemachine not remove COMPLETED flows' checkpoints from the database 
if they are started with a clientId, instead they are getting persisted and retained within 
the database along with their result (`DBFlowResult`).

On flow start with a client id (`startFlowDynamicWithClientId`), if the client id maps to
a flow that was previously started with the same client id and the flow is now finished, 
then fetch the `DBFlowResult` from the database to construct a 
`FlowStateMachineHandle` done future and return it back to the client.

Object stored as results must abide by the storage serializer rules. If they fail to do so
the result will not be stored and an exception is thrown to the client to indicate this.

CORDA-3809 Expose client side unique RPC ID for flow starts (#6307)
Introducing a new flow start method (`startFlowDynamicWithClientId`) passing in a `clientId`.

Once `startFlowDynamicWithClientId` gets called, the `clientId` gets injected into `InvocationContext` and also pushed to the logging context.

If a new flow starts with this method, then a < `clientId` to flow > pair is kept on node side, even after the flow's lifetime. If `startFlowDynamicWithClientId` is called again with the same `clientId` then the node identifies that this `clientId` refers to an existing < `clientId` to flow > pair and returns back to the rpc client a `FlowStateMachineHandle` future, created out of that pair.

`FlowStateMachineHandle` interface was introduced as a thinner `FlowStateMachine`. All `FlowStateMachine` properties used by call sites are moved into this new interface along with `clientId` and then `FlowStateMachine` extends it.

Introducing an acknowledgement method (`removeClientId`). Calling this method removes the < `clientId` to flow > pair on the node side and frees resources.

efd633c7b9 CORDA-3722 withEntityManager can rollback its session (#6187)
* CORDA-3722 withEntityManager can rollback its session

Improve the handling of database transactions when using
`withEntityManager` inside a flow.

Extra changes have been included to improve the safety and
correctness of Corda around handling database transactions.

This focuses on allowing flows to catch errors that occur inside an
entity manager and handle them accordingly.

Errors can be caught in two places:

- Inside `withEntityManager`
- Outside `withEntityManager`

Further changes have been included to ensure that transactions are
rolled back correctly.

Errors caught inside `withEntityManager` require the flow to manually
`flush` the current session (the entity manager's individual session).
By manually flushing the session, a `try-catch` block can be placed
around the `flush` call, allowing possible exceptions to be caught.

Once an error is thrown from a call to `flush`, it is no longer possible
to use the same entity manager to trigger any database operations. The
only possible option is to rollback the changes from that session.
The flow can continue executing updates within the same session but they
will never be committed. What happens in this situation should be handled
by the flow. Explicitly restricting the scenario requires a lot of effort
and code. Instead, we should rely on the developer to control complex
workflows.

To continue updating the database after an error like this occurs, a new
`withEntityManager` block should be used (after catching the previous
error).

Exceptions can be caught around `withEntityManager` blocks. This allows
errors to be handled in the same way as stated above, except the need to
manually `flush` the session is removed. `withEntityManager` will
automatically `flush` a session if it has not been marked for rollback
due to an earlier error.

A `try-catch` can then be placed around the whole of the
`withEntityManager` block, allowing the error to be caught while not
committing any changes to the underlying database transaction.

To make `withEntityManager` blocks work like mini database transactions,
save points have been utilised. A new savepoint is created when opening
a `withEntityManager` block (along with a new session). It is then used
as a reference point to rollback to if the session errors and needs to
roll back. The savepoint is then released (independently from
completing successfully or failing).

Using save points means, that either all the statements inside the
entity manager are executed, or none of them are.

- A new session is created every time an entity manager is requested,
but this does not replace the flow's main underlying database session.
- `CordaPersistence.transaction` can now determine whether it needs
to execute its extra error handling code. This is needed to allow errors
escape `withEntityManager` blocks while allowing some of our exception
handling around subscribers (in `NodeVaultService`) to continue to work.

CORDA-3490 Add option to start node without starting checkpointed flows (#6136)
Added command-line option: `--pause-all-flows` to the Node to control this.
This mode causes all checkpoints to be set to status PAUSED when the
state machine starts up (in StartMode.Safe mode). 

Changed the state machine so that PAUSED checkpoints are loaded into
memory (the checkpoint is deserialised but the flow state is left serialised)
but not started.

Messages from peers are queued whilst the flow is paused and processed
once the flow is resumed.

CORDA-3291 isKilled flag and session errors for killed flows (#6170)
* CORDA-3291 `isKilled` flag and session errors for killed flows

## Summary

Two major improvements have been worked on:

- A new flag named `isKilled` has been added to `FlowLogic` to allow
developers to break out of loops without suspension points.
- Killed flows now send session errors to their counter parties allowing
their flows to also terminate without further coordination.

Achieving these changes required a __fundamental__ change to how flows are
killed as well as how they sleep.

## `isKilled` flag

The addition of `FlowLogic.isKilled` allows flows to check if the
current flow has been killed. They can then throw an exception to lead
to the flow's termination (following the standard error pathway). They
can also perform some extra logic or not throw an exception if they
really wanted to.

No matter what, once the flag is set, the flow will terminate. Due to
timing, a killed flow might successfully process its next suspension
event, but it will then process a killed transition and terminate.

## Send session errors when killing a flow

A flow will now send session errors to all of its counter parties. They
are transferred as `UnexpectedFlowEndException`s. This allows initiated
flows to handle these errors as they see fit, although they should
probably just terminate.

## How flows are killed

### Before

Originally we were relying on Quasar to interrupt a flow's fiber, we
could then handle the resulting `InterruptedException`. The problem with
this solution is that it only worked when a flow was already suspended
or when a flow moved into suspension. Flows stuck in loops did not work.

### After

We now *do not* use Quasar to interrupt a flow's fiber. Instead, we
switch `FlowStateMachine.isKilled` to true and schedule a new event.
Any event that is processed after switching this flag will now cause a
`KilledFlowTransition`. This transition follows similar logic to how
error propagation works. Note, the extra event allows a suspended flow
to be killed without waiting for the event that it was _really_ waiting
for.

This allows a lot of the tidy up code in `StateMachineManager.killFlow`
to be removed as tidy up is executed as part of removing a flow.
Deleting a flow's checkpoint and releasing related soft locks is still
handled manually in case of infinite loops but also triggered as part
of the actions executed in a transition.

This required flow sleeping to be changed as we no longer rely on
quasar.

## How flows now sleep

The reliance on Quasar to make a flow sleep has been removed.

Instead, when a flow sleeps we create a `ScheduledFuture` that is
delayed for the requested sleep duration. When the future executes it
schedules a `WakeUpFromSleep` event that wakes up the flow... Duh.

`FlowSleepScheduler` handles the future logic. It also uses the same
scheduled thread pool that timed flows uses.

A future field was added to `StateMachineState`. This removes the 
need for concurrency control around flow sleeps as the code path does
not need to touch any concurrent data structures.

To achieve this:

- `StateMachineState.future` added as a `var`
- When the `ScheduledFuture` is created to wake up the flow the passed
in `StateMachineState` has its `future` value changed
- When resumed `future` and `isWaitingForFuture` are set to `null` and
`false` respectively
- When cancelling a sleeping flow, the `future` is cancelled and nulled
out. `isWaitingForFuture` is not changed since the flow is ending anyway
so really the value of the field is not important.

CORDA-3722 withEntityManager can rollback its session (#6187)
* CORDA-3722 withEntityManager can rollback its session

## Summary

Improve the handling of database transactions when using
`withEntityManager` inside a flow.

Extra changes have been included to improve the safety and
correctness of Corda around handling database transactions.

This focuses on allowing flows to catch errors that occur inside an
entity manager and handle them accordingly.

Errors can be caught in two places:

- Inside `withEntityManager`
- Outside `withEntityManager`

Further changes have been included to ensure that transactions are
rolled back correctly.

## Catching errors inside `withEntityManager`

Errors caught inside `withEntityManager` require the flow to manually
`flush` the current session (the entity manager's individual session).
By manually flushing the session, a `try-catch` block can be placed
around the `flush` call, allowing possible exceptions to be caught.

Once an error is thrown from a call to `flush`, it is no longer possible
to use the same entity manager to trigger any database operations. The
only possible option is to rollback the changes from that session.
The flow can continue executing updates within the same session but they
will never be committed. What happens in this situation should be handled
by the flow. Explicitly restricting the scenario requires a lot of effort
and code. Instead, we should rely on the developer to control complex
workflows.

To continue updating the database after an error like this occurs, a new
`withEntityManager` block should be used (after catching the previous
error).

## Catching errors outside `withEntityManager`

Exceptions can be caught around `withEntityManager` blocks. This allows
errors to be handled in the same way as stated above, except the need to
manually `flush` the session is removed. `withEntityManager` will
automatically `flush` a session if it has not been marked for rollback
due to an earlier error.

A `try-catch` can then be placed around the whole of the
`withEntityManager` block, allowing the error to be caught while not
committing any changes to the underlying database transaction.

## Savepoints / Transactionality

To make `withEntityManager` blocks work like mini database transactions,
save points have been utilised. A new savepoint is created when opening
a `withEntityManager` block (along with a new session). It is then used
as a reference point to rollback to if the session errors and needs to
roll back. The savepoint is then released (independently from
completing successfully or failing).

Using save points means, that either all the statements inside the
entity manager are executed, or none of them are.

## Some implementation details

- A new session is created every time an entity manager is requested,
but this does not replace the flow's main underlying database session.
- `CordaPersistence.transaction` can now determine whether it needs
to execute its extra error handling code. This is needed to allow errors
escape `withEntityManager` blocks while allowing some of our exception
handling around subscribers (in `NodeVaultService`) to continue to work.

CORDA-3596 Record flow metadata (#6067)
* CORDA-3596 Record flow metadata

Record flow metadata during the zero'th checkpoint that occurs before
calling the flow's `call` function.

This required adding an RPC call's arguments to the `InvocationContext`
that gets created. These arguments are then accessible within the
statemachine and from the `Checkpoint` class. The arguments are then
extracted when recording a flow's metadata inside of
`DBCheckpointStorage`.

Updated the size of the started by column to 128 since it was not long
enough to hold the fully qualified class of a service that started a
flow.

* CORDA-3596 Remove arguments from in-memory checkpoint

When executing a flows first real suspend (from flow code) the arguments
 contained in the `InvocationContext` are removed. This saves holding
 these arguments for the whole lifecyle of a flow.

* CORDA-3596 Increase `cordapp_name` column to 128

* CORDA-3596 Join metadata by `flow_id`

Due to changes in where metadata is recorded, there is no need for
having `invocation_id` as the metadata table's primary key. The
`flow_id` is now the primary key of the table and is used to join to the
 main checkpoints table.

The `invocation_id` has been removed from the checkpoints table since it
 is not needed for the join anymore.

* CORDA-3596 Remove `received_time` from metadata table

* CORDA-3596 Remove unused `StartReason` enum

* CORDA-3596 Simple `DBCheckpointStorageTests` for metadata

* CORDA-3596 Truncate really long flow names

4bae045a58 ENT-4601 Public API to run external operations from a flow (#5833)
Deprecate FlowAsyncOperation and reimplement public versions FlowExternalOperation and FlowExternalAsyncOperation.

await added to FlowLogic to allow easy calling from both Java and Kotlin. There are two overrides of await (one for FlowExternalOperation and FlowExternalAsyncOperation).

Implementations of FlowExternalOperation return a result (written as blocking code) from their execute function. This operation will then be executed using a thread provided by the externalOperationExecutor.

Implementations of FlowExternalAsyncOperation return a future from their execute function. This operation must be executed on a newly spawned thread or one provided by a thread pool. It is up to developers to handle threading in this scenario.

The default thread pool (externalOperationExecutor) can be configured through the flowExternalOperationThreadPoolSize node config.

The current implementation leaves FlowAsyncOperation alone, meaning that any developers that have used it (even though it is internal) won't need to change their apps. If this was not concern I would delete it completely and replumb the state machine code. Instead, it has been marked with @DoNotImplement and executeAsync is annotated with @Deprecated

a7147c1ffd ENT-4652: Provide an "attachment fixup" mechanism to repair broken transactions. (#5825)
* Do not register cordapp custom serialisers when using attachment classloader.

* Record the URLs of CorDapp JARs that contain custom serialisers. Include these JARs as extra attachments if we discover that we're missing a custom serialiser during transaction verification.

* Check for disabled serializer when explicitly requesting a custom serializer.
Refactor test case to force use of a custom serializer.

* Tidy up basic custom serializer test.

* Also test that TransactionBuilder rejects missing custom serializers.

* Remove test whitelists, which should not be needed with custom serialisers.

* Add changelog entry. Also align TestCordappImpl.findRoots() with OS backports.

* Second approach based around CorDapps inside AttachmentStorage - report missing type descriptor or any non-composable types.

* Initial implementation of Corda-Fixup rules inside a CorDapp jar.

* Replace original "automatic attachment fixing" mechanism completely.

* First review comments: restore "missing class" logic to TransactionBuilder.

* Restore "missing class" mechanism as fallback for SignedTransaction too.

CORDA-3124: Ensure transaction is fully verified before sending to notary (#5516)
NotaryFlow.Client flow assumes the passed transaction is verified, which is
the case when it's invoked as a sub-flow in FinalityFlow. However,
NotaryFlow.Client can also be called directly from any custom flow, so
we need to ensure it performs transaction verification to avoid accidentally
sending an invalid transaction to a non-validating notary.
