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.
