[Pacemaker] Node sends shutdown request to other node:error: handle_request: We didn't ask to be shut down, yet our DC is telling us too

Thanks Digimer. I will make sure that I configure fencing along with CMAN.
I have multiple independent master slave resources in the cluster.
A node could be master for few and slave for other resources.
I need to make sure that fencing occurs at resource level
(no klling of nodes) rather than at node level.I hope it is ok to embed
logic of selective blocking of resources in  fencing agent.
