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.
