    Stop leaking ceph df cmd in RBD utils

    If the ceph df command fails in the get_pool_info
    method of RBD utils the actual command executed
    if seen by the users in the fault error message.

    This hides the command behind a StorageError
    exception and logs the exception instead of leaking
    it to the users.
