--------------------------------------------------------------------
Thanks [~elek] for the confirmation.
As per offline discussion with [~jnp], removed the ExecutorMap in
XceiverServerRatis with a list in patch v6. Fixed the
CloseContainerHandlingByClient tests and removed the TestContainerStateMachine
tests which were basically verifying the synchronization between write chunks,
putBlock and CloseContainer as with this Jira, there won' be any such
synchronization required.
Other test failures are not related.

> As part of handling Node failures in Ozone, the block commit need to happen
> in order inside ContainerStateMachine per container. With RATIS-341, it is
> guaranteed that the applyTransaction calls for committing the write chunks
> will be initiated only when the WriteStateMachine data for write Chunk
> operations finish.
> This Jira is aimed at making all the applyTransaction operations inside
> ContainerStateMachine serial per container with a single thread Executor per
> container handling all applyTransactions calls.
