Disable VIPs before stopping cluster during version upgrade
If "pcs cluster stop --all" is executed on a controller that happens to have a VIP on the internal network, pcs may use the VIP as the source address for communication with another cluster node. When pacemaker is stopped this VIP goes away, and pcs never receives a response from the other node. This causes pcs to hang indefinitely; eventually the upgrade times out and fails. Disabling the VIPs before stopping the cluster avoids this situation. Change-Id: I6bc59120211af28456018640033ce3763c373bbb Closes-Bug: 1577570
