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.
