> 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.
