BZ #1082811 - HA Keystone improvements, cont'd.

https://bugzilla.redhat.com/show_bug.cgi?id=1082811

Tweaks.  Add and use the template for the bash script
/tmp/ha-all-in-one-util.bash that contains logic to assist with puppet
flow.  Simplify quickstack::pacemaker::rsync -- end result of waiting
for the non-vip servers to sync up is the same.
