Commit 0c5b1c27f26a008baedac4eb0c69f9b01080eaec in nifi's branch

NIFI-1464, Refactored Processor's life-cycle operation sequence
* Simplified and cleaned StandardProcessScheduler.start/stopProcessor methods
* Added stop/start operations to ProcessorNode.
* Removed unnecessary synchronization blocks related to ScheduledState in favor
of enforcing order and idempotency via CAS operations. Those synchronization
blocks were causing intermittent deadlocks whenever @OnScheduled blocks
indefinitely.
* Added support for stopping the service when @OnScheduled operation hangs.
* Fixed the order of life-cycle operation invocation ensuring that each
operation can *only* be invoked at the appropriate time
* Removed unnecessary locks from StandardProcessNode since Atomic variables are
used.
* Removed calls to @OnStopped from ContinuallyRunningProcessTask while ensuring
that procesor's full shut down in implementation of
StandardProcessorNode.stop() method.
* Removed dead code
* Added comprehensive tests suite that covers 95% of Processor's life-cycle
operations within the scope of FlowController, StandardProcesssScheduler and
StandardProcessNode
* Improved and added javadocs on covered operations with detailed explanations.

> Similar lifecycle handling improvements that went in as part of the NIFI-1164
> for ControllerServices, could/should be applied to other components (e..g,
> Processors).
> The improvements may also help to address NIFI-78 (may be without killing the
> thread).
