      Description

      Implement the Provided Storage Mount Manager. This is a service (thread) in the Namenode that manages backup mounts, unmounts, snapshotting, and monitoring the progress of backups.

      On mount, the mount manager writes XATTR information at the top level of the mount to do the appropriate bookkeeping. This is done to maintain state in case the Namenode falls over.
