In more targeted testing of OSP10 minor update we found out there is an issue with way pacemaker services are created and how we defined the order constraints. We will have to provide fix for all the releases of OSP, but for OSP10 we probably will go with workaround I created and tested. Issue is pacemaker resource order constraints are kind Optional which means they do not apply on shutdown of pacemaker cluster on the node. This causes haproxy to be stopped before the VIP is migrated away from the node and subsequent APIs failure. Migration of VIPs will be applied in yum_update.sh script but we should also update the reboot documentation/procedure for the operators.

OSP12 is EOL and we fixed this in the other versions, so closing.

Let me know if you need to discuss this.
