    ctdb: add test script for ctdb_mutex_ceph_rados_helper
    
    This standalone test script performs the following:
    - using ctdb_mutex_ceph_rados_helper, take a lock on the Ceph RADOS
      object a CLUSTER/$POOL/$OBJECT using the Ceph keyring for $USER
      + confirm that lock is obtained, via ctdb_mutex_ceph_rados_helper "0"
        output
    - check RADOS object lock state, using the "rados lock info" command
    - attempt to obtain the lock again, using ctdb_mutex_ceph_rados_helper
      + confirm that the lock is not successfully taken
    - tell the first locker to drop the lock and exit, via SIGTERM
    - once the first locker has exited, attempt to get the lock again
      + confirm that this attempt succeeds

    ctdb: cluster mutex helper using Ceph RADOS
    
    ctdb_mutex_ceph_rados_helper implements the cluster mutex helper API
    atop Ceph using the librados rados_lock_exclusive()/rados_unlock()
    functionality.
    
    Once configured, split brain avoidance during CTDB recovery will be
    handled using locks against an object located in a Ceph RADOS pool.

    Disable generation/installation of the etcd cluster mutex helper by
    default. Support can be explicitly enabled at configure time with
    --enable-etcd-reclock.
