* Restrict Gradle dependency locations so Gradle does not check Corda/Kotlin specific repositories for other dependencies, to save on wasted requests.

Dummy package names cause build failure as they are not found on the classpath when trying to import them. Now that empty package name list is allowed, the dummy names are removed.
* CORDA-3663 MockServices crashes when two of the provided packages to scan are deemed empty in 4.4 RC05
this happends when a given package is not found on the classpath. Now it is handled and an exception is thrown
* replace dummy package names in tests with valid ones
* allow empty package list for CustomCordapps and exclude those from the created jars
* detekt fix
* always true logic fix
* fix to check for empty packages instead of empty classes
* fix for classes and fixups
* logic refactor because of detekt stupidity

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.
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: 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.
