[ClusterLabs] active/passive resource config

[Strahil Nikolov]

 A resource group is a perfect candidate for a group and should work quite well.Keep in mind that:1. This systemd service must be disabled on both nodes as the cluster will controll it2. Test in advance that the systemd service can start on each node3. You can add run_arping=true for the IP resource in order to learn if there is an IP collision.4. You can also consider adding default resource stickiness.
What do you mean that the setup is not acting as expected?

------------------pcs resource create A systemd:myservice   op  start  interval=0s  timeout=20s   monitor  interval=10s  timeout=20s   stop  interval=0s timeout=20s meta migration-threshold=3  failure-timeout=60

pcs resource create vip ocf:heartbeat:IPaddr2 ip=192.168.2.87 cidr_netmask=24 op monitor interval=20s  meta resource-stickiness=100

pcs constraint colocation add vip A INFINITY
