[Pacemaker] Failure after intermittent network outage

[Andrew Beekhof]

Your basic problem is this...

Mar  1 11:17:21 wapgw1-2 pengine: [5748]: WARN: unpack_rsc_op:
Processing failed op vm-mproxy1-1_monitor_0 on wapgw1-log: unknown
error (1)

We asked what state the resource was in and it replied "arrrggghhhh"
instead of "not installed".
Had it replied with not installed, we'd have no reason to call stop or
fence the node to try and clean it up.
