> With quasi closed container state for handling majority node failures, the close container
handling sequence in Datanodes need to change. Once the datanodes receive a close container
command from SCM, the open container replicas individually be marked in the closing state.
In a closing state, only the transactions coming from the Ratis leaderĀ  are allowed , all
other write transaction will fail. A close container transaction will be queued via Ratis
on the leader which will be replayed to the followers which makes it transition to CLOSED/QUASI
CLOSED state.
