Retain "recovery lock" and mark as deprecated for backward

Some documentation is still inconsistent.

ce289e89e5 ctdb_mutex_ceph_rados_helper: fix deadlock via lock renewals
RADOS locks without expiry persist indefinitely. This results in CTDB
deadlock during failover if the recovery master dies unexpectedly, as
subsequently elected recovery master nodes can't obtain the recovery
lock.
Avoid deadlock by using a lock expiration time (10s by default), and
renewing it periodically.

node1$ touch /path/to/cluster-fs/FILE

node1$ ./bin/ping_pong -l /path/to/cluster-fs/FILE
Holding lock, press any key to continue...
You should run the same command on another node now.

node2$ ./bin/ping_pong -l /path/to/cluster-fs/FILE

Output can either be:

  Holding lock, press any key to continue...

This means POSIX byte range locks are *not* working.

If you see this instead:

  file already locked, calling check_lock to tell us who has it locked...:
  check_lock failed: lock held: pid='27375', type='1', start='0', len='0'
  Working POSIX byte range locks
