Integrate `DBFlowException` with the rest of the checkpoint schema, so now
we are saving the flow's exception result in the database.
Making statemachine not remove `FAILED` flows' checkpoints from the
database if they are started with a clientId.
Retrieve the DBFlowException from the database to construct a
`FlowStateMachineHandle` future and complete exceptionally the flow's result
future for requests (`startFlowDynamicWithClientId`) that pick FAILED flows ,
started with client id, of status Removed.
On killing a flow the client id mapping of the flow gets removed.
The storage serialiser is used for serialising exceptions. Note, that if an
exception cannot be serialised, it will not fail and will instead be stored
as a `CordaRuntimeException`. This could be improved in future
changes.

* allow empty package list for CustomCordapps and exclude those from the created jars

* PR related minor refactors
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.

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.

* CORDA-3291 `isKilled` flag and session errors for killed flows
## Summary
Two major improvements have been worked on:
- A new flag named `isKilled` has been added to `FlowLogic` to allow
developers to break out of loops without suspension points.
- Killed flows now send session errors to their counter parties allowing
their flows to also terminate without further coordination.
Achieving these changes required a __fundamental__ change to how flows are
killed as well as how they sleep.
## `isKilled` flag
The addition of `FlowLogic.isKilled` allows flows to check if the
current flow has been killed. They can then throw an exception to lead
to the flow's termination (following the standard error pathway). They
can also perform some extra logic or not throw an exception if they
really wanted to.
No matter what, once the flag is set, the flow will terminate. Due to
timing, a killed flow might successfully process its next suspension
event, but it will then process a killed transition and terminate.
## Send session errors when killing a flow
A flow will now send session errors to all of its counter parties. They
are transferred as `UnexpectedFlowEndException`s. This allows initiated
flows to handle these errors as they see fit, although they should
probably just terminate.
## How flows are killed
### Before
Originally we were relying on Quasar to interrupt a flow's fiber, we
could then handle the resulting `InterruptedException`. The problem with
this solution is that it only worked when a flow was already suspended
or when a flow moved into suspension. Flows stuck in loops did not work.
### After
We now *do not* use Quasar to interrupt a flow's fiber. Instead, we
switch `FlowStateMachine.isKilled` to true and schedule a new event.
Any event that is processed after switching this flag will now cause a
`KilledFlowTransition`. This transition follows similar logic to how
error propagation works. Note, the extra event allows a suspended flow
to be killed without waiting for the event that it was _really_ waiting
for.
This allows a lot of the tidy up code in `StateMachineManager.killFlow`
to be removed as tidy up is executed as part of removing a flow.
Deleting a flow's checkpoint and releasing related soft locks is still
handled manually in case of infinite loops but also triggered as part
of the actions executed in a transition.
This required flow sleeping to be changed as we no longer rely on
quasar.
## How flows now sleep
The reliance on Quasar to make a flow sleep has been removed.
Instead, when a flow sleeps we create a `ScheduledFuture` that is
delayed for the requested sleep duration. When the future executes it
schedules a `WakeUpFromSleep` event that wakes up the flow... Duh.
`FlowSleepScheduler` handles the future logic. It also uses the same
scheduled thread pool that timed flows uses.
A future field was added to `StateMachineState`. This removes the
need for concurrency control around flow sleeps as the code path does
not need to touch any concurrent data structures.
To achieve this:
- `StateMachineState.future` added as a `var`
- When the `ScheduledFuture` is created to wake up the flow the passed
in `StateMachineState` has its `future` value changed
- When resumed `future` and `isWaitingForFuture` are set to `null` and
`false` respectively
- When cancelling a sleeping flow, the `future` is cancelled and nulled
out. `isWaitingForFuture` is not changed since the flow is ending anyway
so really the value of the field is not important.
