[ClusterLabs] Make sure either 0 or all resources in a group are running

[Sam Gardner]

Is there any way to modify the behavior of a resource group N of A, B, and C so that either A, B, and C are running on the same node, or none of them are?

With Pacemaker 1.1.12 and Corosync 1.4.8, if a group N is defined via:
pcs resource group N A B C

if resource C cannot run, A and B still do.
