> When a close Container command request comes to a Datanode (via SCM hearbeat response)
through the Ratis protocol, all the prior enqueued "Write" type of request like putKey, WriteChunk,
DeleteKey, CompactChunk etc should be executed first before CloseContainer request gets executed.
This synchronization needs to be handled in the containerStateMachine. This Jira aims to address
this.
