Remove memory leak endurance test as it spends 8 minutes testing a single failure case that's not end user visible,
and ultimately manifests elsewhere in test failures (which is where this came from in the beginning). It was a good
idea to confirm the change fixed the issue, but this isn't critical enough to retain.
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.
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: Apply new fetch logic to nm updater
* CORDA-3844: Fix base url and warnings
* 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.
