      This is a task for implementing the command line interface for attaching a PROVIDED storage backup system (see HDFS-9806, HDFS-12090).

      1. The administrator should be able to mount a PROVIDED storage volume from the command line.
        hdfs attach -create [-name <name>] <hdfs directory to backup> <backup path (external)>
      2. Whitelist of users who are able to manage mounts (create, attach, detach).
      3. Be able to interrogate the status of the attached storage (last time a snapshot was taken, files being backed up).
      4. The administrator should be able to remove an attached PROVIDED storage volume from the command line. This simply means that the synchronization process no longer runs. If the administrator has configured their setup to no longer have local copies of the data, the blocks in the subtree are simply no longer accessible as the external file store system is currently inaccessible.
        hdfs attach -remove <name> [-force | -flush]
