[ClusterLabs] IPaddr2 cloning inside containers

[Ken Gaillot]

FYI, I stumbled across a report of a suspected kernel issue breaking
iptables clusterip inside containers:

    https://github.com/lxc/lxd/issues/2773

ocf:heartbeat:IPaddr2 uses clusterip when cloned. I'm guessing no one's
tried something like that yet, but this is a note of caution to anyone
thinking about it.

Pacemaker's new bundle feature doesn't support cloning the IPs it
creates, but that might be an interesting future feature if this issue
is resolved.
