-------------------------------------------------------------
Thanks [~arpitagarwal] and [~bharatviswa] for reviews.
I have updated patch v05 to handle the create and update container file cases
separately. Thanks Bharat for catching it.
The test failures are unrelated to this patch and pass locally.

> During container update and close, the .container file on disk is modified.
> We should make sure that the in-memory state and the on-disk state for a
> container are consistent.
> A write lock is obtained before updating the container data during close or
> update operations.
> During update operation, if the on-disk update of .container file fails, then
> the container metadata is in-memory is also reset to the old value.
> During close operation, if the on-disk update of .container file fails, then
> the in-memory containerState is set to CLOSING so that no new operations are
> permitted.
