> Implement SharedCount or sequencer API using jetcd.
> CheckpointIDCounter is used to get and increment an integer atomically for creating checkpoint ID. Zookeeper based CheckpointIDCounter chooses SharedCount API in curator to achieve its target. While I find the implementation of SharedCount in curator somewhat complicated considering flink's use case, I think a sequencer API is adequate for the need of CheckpointIDCounter.
