…ter update, it ends up in a state of STARTING. If the parameter is then
updated again, it transitions the state to STOPPING but the processor is not
fully stopped yet. At that point, the parameter is updated and the processor is
attempted to be started again. Fixed this by keeping the number of active
threads to >= 1 if processor is STOPPING in order to convey that it is not
fully stopped. Also addressed a few minor bugs discovered in the process: when
stopping a processor, if status == invalid, it should be skipped instead of
waiting for the status to become stopped since it never will be. In the DTO's
run status use Stopped instead of Invalid if there is at least 1 active thread
/ if stopping but not stopped. When considering if a processor has transitioned
to the desired state for parameter updates, do not consider validation status
if still transitioning to stopped or if the desired state has already been
reached. Added new system tests to verify behavior.
