NIFI-14654 Fixed Stateless Process Group session lifecycle handling (#10014)
Ensure when a Stateless Process Group is stopped that we properly call all
success and/or failure session callbacks before stopping the Processor. In
order to make system tests to verify this more straight-forward, also exposed
the CounterRepository such that system tests can obtain counter values to
ensure that methods are called appropriately.

> If a Processor commits a session using {{ProcessSession.commitAsync(Runnable,
> Consumer<Throwable>)}} but the Stateless Process Group is stopped, sometimes
> the Processor's @OnStopped method is called before the Runnable or
> Consumer<Throwable> is called. This can cause the @OnStopped method to behave
> incorrectly, effectively running while the Processor is still being triggered.
