------------------------------------
Hello [~anu], [~xyao]
Appreciate if you can help to review this patch, I implemented
{{UpdateContainer}} call in the dispatcher, it behaves like
# Throws CONTAINER_NOT_FOUND error if the container doesn't exist
# Throws NO_SUCH_ALGORITHM if the digest algorithm not found
# Throws UNSUPPORTED_REQUEST if tries to update a closed container
# Throws CONTAINER_INTERNAL_ERROR if some other error happens during the update
# Updates an existing container with the given container data, if succeed, both
container map and data on disk updated
# Backup the container file first, if update fails, restores the container file
from the backup
For test
# Added an unit test {{TestContainerPersistence#testUpdateContainer}}
# Added some code in {{TestOzoneContainer#testOzoneContainerViaDataNode}} to
verify client server request/response.
