Add more intelligence to fence daemon to avoid fencing nodes
when we detect conditions where it might be likely.

When fence victims are added following a node /joining/ the fence
domain [rather than the usual of victims added following a node
failing], its a good clue that other nodes may be in the process
of joining the cluster and therefore unfairly marked for fencing.

When this is detected, delaying for a configurable number of seconds
before doing the actual fence operation can allow victim nodes some
time to join the cluster and avoid being fenced. The default delay
in this event is now at 3s, but increasing it to 10s may be better.

It can optionally be set in cluster.conf by adding:

<fence_daemon delay="10">
</fenced_damon>
