In order to make use of alternate ways to manage ctdb cluster lock we put the traditional method of holding it inside a shared file system behind a conditional which can be optionally specified in settings yaml. Signed-off-by: Anoop C S <[email protected]>

With cephfs.data.ctdb_mutex set to 'rados' we make use of dedicated ctdb_mutex_ceph_rados_helper binary to manage cluster lock. See manual page[1] for more details. [1] https://ctdb.samba.org/manpages/ctdb_mutex_ceph_rados_helper.7.html Signed-off-by: Anoop C S <[email protected]>

It has been a while since a dedicated helper got added to CTDB for managing cluster locks directly on ceph RADOS. Therefore provide a mechanism to optionally configure it instead of the default shared file system locks.
See man ctdb_mutex_ceph_rados_helper(7) for more details.
