Update to the LVS eventscript.
Do not assume all nodes are members of LVS so always deciding the recmaster will be lvsmaster wont work.
Instead,
Create the set of active LVS nodes as those nodes that are LVS capable and
also HEALTHY.
Except if ALL LVS capable nodes are unhealthy in which case we allow the unhealthy
nodes to be part of the active set.
In the active set, pick one of the active nodes as being the lvsmaster
which will receive all incoming traffic and distribute it across
the active lvs nodes in the cluster.
(This used to be ctdb commit b2ccb891b81b041e2186e038b67bb4354b7892aa)
