updated pacemaker/neutron.pp manifests to do ovs/netns cleanups.

Using ocf scripts the cleanups handle the cleanup of agent
resources (qrouter, qdhcp, etc..) when those are migrated to
different hosts.
BZ #1120602 - Add neutron-agent-cleanup ocf resources to Pacemaker config.

https://bugzilla.redhat.com/show_bug.cgi?id=1120602

The quickstack resource wrapper is needed for the previous patch to work properly.
