Martin Schwenke 73555e8248 ctdb-recoverd: Use race for cluster lock as election when lock is enabled 
If the cluster is partitioned then nodes in one partition can not take
the lock anyway, so election is pointless.  It just introduces
unnecessary corner cases.

Instead just race for the lock.

When a node notices a lack of leader and notifies other nodes of an
election via an unknown leader broadcast, the cluster lock election is
hooked into this broadcast.

The test needs to be updated because losing the cluster lock can now
result in a leadership change.
