When an incorrect message is received, the flow should resume to allow
it to throw the error back to user code and possibly cause the flow to
fail.
For now, if an `EndSessionMessage` is received instead of a
`DataSessionMessage`, then an `UnexpectedFlowEndException` is thrown
back to user code. Allowing it to correctly re-enter normal flow error
handling.
Without this change, the flow will hang due to it failing while creating
a transition which exists outside of the general state machine error
handling code path.
Sessions are now terminated after performing the original
`FlowIORequest` passed into `StartedFlowTransition`, instead of before.
This is done by scheduling an `Event.TerminateSessions` if there are
sessions to terminate when performing a suspending event.
Originally this was done by hijacking a transition that is trying to
perform a `StartedFlowTransition`, terminating the sessions and then
scheduling another `Event.DoRemainingWork` to perform the original
transition. This introduced a bug where, another event (from a external
message) could be placed onto the queue before the
`Event.DoRemainingWork` could be added. In most scenarios, that should
be ok. But, if a flow is retrying (while in an uninitiated state) and
this occurs the flow could fail due to being in an unexpected state.
Terminating the sessions after performing the original transition
removes this possibility. Meaning that a restarting flow will always
perform the transition they supposed to do (based on the called
suspending event).

Correct race condition in FlowVersioningTest where the last message is read (and the session close can be triggered)
before one side has finished reading metadata from the session.
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.

* CORDA-3844: Change response object and response validation
In order to make sure that the returned node infos are not maliciously modified, either a signed list response
or a signed reference object would need to be provided. As providing a signed list requires a lot of effort from NM and Signer services,
the signed network map is provided instead, allowing nodes to validate that the list provided conforms to the entries of the signed network map.

Refactor `FlowStateMachineImpl.transientValues` and
`FlowStateMachineImpl.transientState` to stop the fields from exposing
the fact that they are nullable.
This is done by having private backing fields `transientValuesReference`
and `transientStateReference` that can be null. The nullability is still
needed due to serialisation and deserialisation of flow fibers. The
fields are transient and therefore will be null when reloaded from the
database.
Getters and setters hide the private field, allowing a non-null field to
returned.
There is no point other than in `FlowCreator` where the transient fields
can be null. Therefore the non null checks that are being made are
valid.
Add custom kryo serialisation and deserialisation to `TransientValues`
and `StateMachineState` to ensure that neither of the objects are ever
touched by kryo.

Cancel the future being run by a flow when finishing or retrying it. The
cancellation of the future no longer cares about what type of future it
is.
`StateMachineState` has the `future` field, which holds the 3
(currently) possible types of futures:
- sleep
- wait for ledger commit
- async operation / external operation
Move the starting of all futures triggered by actions into
`ActionFutureExecutor`.
* Add schema migration to smoke tests
* Fix driver to work correctly for out-of-proc node with persistent database.

Changes to `TopLevelTransition` after merging from earlier releases.
When a flow is kept for observation and its checkpoint is saved as
HOSPITALIZED in the database, we must acknowledge the session init and
flow start events so that they are not replayed on node startup.
Otherwise the same flow will be ran twice when the node is restarted,
one from the checkpoint and one from artemis.
Reduce exception_message and stack_trace lengths in table node_flow_exceptions from 4000 to 2000 to fix Oracle failing with: 'ORA-00910: specified length too long for its datatype'
These tests were removed after doing a merge from 4.4. They needed
updating after the changes from 4.4 anyway. These have been included in
this change.
Also fix kill flow tests and send initial tests.
When an uncaught exception propagates all the way to the flow exception
handler, the flow will be forced into observation/hospitalised.
The updating of the checkpoints status is done on a separate thread as
the fiber cannot be relied on anymore. The new thread is needed to allow
database transaction to be created and committed. Failures to the status
update will be rescheduled to ensure that this information is eventually
reflected in the database.
