605347faf6 ctdb-takeover: IPAllocAlgorithm replaces LCP2PublicIPs, DeterministicIPs
Introduce a single new tunable IPAllocAlgorithm to set the IP
allocation algorithm.  This defaults to 2 for LCP2 IP address
allocation.

Tunables LCP2PublicIPs and DeterministicIPs are obsolete.

9166c30a41 ctdb-daemon: Rename EventScriptTimeoutCount to MonitorTimeoutCount
This only applies to monitor events so renaming clarifies this.

Note that this change is not backward compatible.  Users with

  CTDB_SET_EventScriptTimeoutCount=<n>

in their configuration will get failures when starting CTDB but the
cause will be clearly logged.

134ede80e8 ctdb-doc: Correct documentation for tunables for script timeout
* The defaults for EventScriptTimeout and EventScriptTimeoutCount are
  wrong.

* EventScriptTimeout is the total time for all enabled scripts that
  are run for an event, not a single event script.

* EventScriptTimeoutCount only applies to monitor events.

* EventScriptUnhealthyOnTimeout is obsolete, so remove it.

d110fe2318 ctdb-daemon: Mark tunable VerifyRecoveryLock as obsolete
It is pointless having a recovery lock but not sanity checking that it
is working.  Also, the logic that uses this tunable is confusing.  In
some places the recovery lock is released unnecessarily because the
tunable isn't set.

Simplify the logic by assuming that if a recovery lock is specified
then it should be verified.

Update documentation that references this tunable.
