Configure libgfapi access when cinder_backend_gluster is set

Setting qemu_allowed_storage_drivers=gluster in the nova config causes
libvirt/qemu to mount gluster volumes via libgfapi.
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.

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

BZ #1123314 - pacemaker heat op monitor interval to 60s

From BZ: "Rubygem-staypuft: HA: Relax the openstack-heat-engine: op
monitor interval to 60 seconds.

Now it's openstack-heat-engine: op monitor interval=30s

appears to be too resource consuming in some cases (like
openstack-heat-engine and causes false positives."
BZ #1123318 - HA: set max_retries=-1 for accessing the DB

https://bugzilla.redhat.com/show_bug.cgi?id=1123318

Services will now continue to retry accessing the db on startup if it
is not available, as the max_retries configuration value in the
openstack .conf files is now set to -1.

From BZ:
"HA: All services are missing max_retries=-1 settings for accessing the DB.

This means that if the DB is not started before the service, the
service will fail to start. This behaviour is currently mitigated by:
start-failure-is-fatal: false, but it is technically incorrect."

Make quickstack::neutron::all contain neutron::server, so that
resources after quickstack::neutron::all also are after
neutron::server.

BZ#1127816 - HA neutron sets pcs properties before starting service
do not provide a default for network_public_network

If quickstack::nova_network::compute is called with network_public_iface
set but no value provided for network_public_network, the default value
for network_public_network will be used in the call to find_nic(), which
will in almost all cases cause find_nic() to return an empty value.

This patch resolves that problem by removing the default setting for
network_public_network.
