      Description

      In order to save CPU cycles and reduce disk and network I/O, we should try to cancel local checkpoint operations belonging to discarded aborted or subsumed checkpoints. For example, if a Task declines a checkpoint, the CheckpointCoordinator will discard this checkpoint. However, other checkpointing operations belonging to this checkpoint won't be necessarily notified and canceled.

      The notification mechanism could piggy back on the existing CancelCheckpointMarker or be a separate signal sent to all participating Tasks.
