[backport] [FLINK-5063] Discard state handles of declined or expired state handles This is backport of #2812 for the release-1.1 branch. Whenever the checkpoint coordinator receives an acknowledge checkpoint message which belongs to the job maintained by the checkpoint coordinator, it should either record the state handles for later processing or discard to free the resources. The latter case can happen if a checkpoint has been expired and late acknowledge checkpoint messages arrive. Furthermore, it can happen if a Task sent a decline checkpoint message while other Tasks where still drawing a checkpoint. This PR changes the behaviour such that state handles belonging to the job of the checkpoint coordinator are discarded if they could not be added to the PendingCheckpoint.
