------------------------------------
Here is my understanding about when to delete a snapshot, first is when
`KafkaRaftClient.pollCurrentState`, the second is when a follower complete
fetching snapshot. is that right? [~jsancio]
> Delete snapshots if it's end offset is less than the log start offset
