Created a database snapshot of a clean Corda OS 4.5.1 database, which can now be used for testing by both the node driver and mock network.
The MockNetwork was changed from using an in memory database to using an on disk database, and makes use of the snapshot to speed up setup times.
The Node Driver was changed from defaulting to an in-memory database to defaulting to an on-disk database. Tests that do not specify the type of database to use will thus use an on-disk database. Tests that opt in for an in-memory database will continue to use an in-memory database as before.
The database snapshots are copied to the node directory inside the build folder, therefore, they should be cleaned up after a build.

Enable reloading of a flow after every checkpoint is saved. This
includes reloading the checkpoint from the database and recreating the
fiber.
When a flow and its `StateMachineState` is created it checks the node's
config to see if the `reloadCheckpointAfterSuspend` is set to true. If it is
it initialises `StateMachineState.reloadCheckpointAfterSuspendCount`
with the value 0. Otherwise, it remains `null`.
This count represents how many times the flow has reloaded from its
checkpoint (not the same as retrying). It is incremented every time the
flow is reloaded.
When a flow suspends, it processes the suspend event like usual, but
it will now also check if `reloadCheckpointAfterSuspendCount` is not
`null` (that it is activated) and process a
`ReloadFlowFromCheckpointAfterSuspend`event, if and only if
`reloadCheckpointAfterSuspendCount` is greater than
`CheckpointState.numberOfSuspends`.
This means idempotent flows can reload from the start and not reload
again until reaching a new suspension point.
Flows that skip checkpoints can reload from a previously saved
checkpoint (or from the initial checkpoint) and will continue reloading
on reaching the next new suspension point (not the suspension point that
it skipped saving).
If the flow fails to deserialize the checkpoint from the database upon
reloading a `ReloadFlowFromCheckpointException` is throw. This causes
the flow to be kept for observation.

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.

Wait for log file to indicate that a driver node process is running, instead of trying to open a socket on the port the node is attempting to binding on. This means the driver is more responsive to the node being ready, as well as removing a race condition where the binding test could block the node from starting.
As sometimes nodes do not log this information, after 20 seconds we presume the node is up.

Maven central will not allow the node-driver to be published without a Javadoc `.jar` file, even if it is empty. This adds an empty Javadoc `.jar` to the output.
In enterprise, `AuthDBTests` picked up a schema from a unit test and
included it in the cordapp it builds. This schema does not have a
migration and therefore fails the integration tests.
`NodeBasedTest` now lets cordapps to be defined and passed in to avoid
this issue. It defaults to making a cordapp from the tests base
directory if none are provided.
* 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.

Removing the ability to initialise schema from the node config, and add a new sub-command to initialise the schema (that does not do anything else and exits afterwards).
Also adding a command line flag that allow app schema to be maintained by hibernate for legacy cordapps, tests or rapid development.
Patching up mock net and driver test frameworks so they create the required schemas for tests to work, defaulting schema migration and hibernate schema management to true to match pre-existing behaviour.
Modified network bootstrapper to run an initial schema set-up so it can register nodes.
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.

## 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.
