[backport] [FLINK-5158] [ckPtCoord] Handle exceptions from
CompletedCheckpointStore in CheckpointCoordinator
Backport of the #2872 for the release 1.1 branch.
Handle exceptions from the CompletedCheckpointStore properly in the
CheckpointCoordinator. This
means that in case of an exception, the completed checkpoint will be
properly cleaned up and also
the triggering of subsequent checkpoints will be started.
