There are some methods related to“get”a CompleteCheckpoint, such as “createPendingCheckpoint/reportToStateTracker/sendAbortedMessage/sendAcknowledgeMessages”. However, these methods sometime use `CheckpointBrief`, sometime uses `tasksTowaitFor/tasksToTriggerFor`, which are the internal state of the `CheckpointCoordinator`. After we refactor maybe all the methods could only use the `CheckpointBrief` as their parameter. (I think CheckpointId,TimeStamps should also be in the CheckpointBrief).
