Restart only services that need it
Restart only services that need it

With new pacemaker architecture, Puppet handles restarts of most of the
services. There are several still managed by pacemaker which need
special restart handling utilizing pacemaker and its resource
agents.

The counterpart in puppet-tripleo requests restarts for individual
pacemaker-managed services by writing out "restart flag" files, and the
pacemaker_resource_restart.sh script then performs the restarts.
