Low: crmd: cl#5064 - Loss of cpg in process list should be reflected …

…in node status.

The node's ha status should be updated to 'dead' when cpg is lost.
When corosync is in use, it is possible that the membership layer
will not report a node has entered/left the cluster when a node
leaves the cpg.  This occurs for a node when pacemaker terminates
unexpectedly while corosynce remains up.  Because of this the
ha status remained "active" even though the cpg for that node
was known to be gone.
