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.
BZ #1126447 - Fix nova scheduler constraints for A/P

https://bugzilla.redhat.com/show_bug.cgi?id=1126447

When setting the scheduler to A/P, the resource name is different than when it
is A/A.  Update constraint creation to account for this.
Add facts for host pacemaker properties

This exposes some pacemaker property information through facter.
There are two main types.

(1) For each cluster member, a fact named pcs_props_<member name>,
which is a comma-separated string similar to the output of "pcs
property show".

(2) For each cluster service, a fact named pcs_setup_<service name>,
which is a boolean indicating whether that service is present on *all*
cluster members.

BZ #1123303 - Add manage_service settings to get puppet out of the way.

https://bugzilla.redhat.com/show_bug.cgi?id=1123303

This does not include rabbit, due to unique issues with that service.
This patch should make starting services more consistent for the included
services as pacemaker will have full control of starting and stopping the
services without the chance of puppet having already done so, which potentially
could cause confusion for pacemaker.

BZ#113272 - Cinder volume active/active should be avoided

https://bugzilla.redhat.com/show_bug.cgi?id=1132722

There's a bug reported against Cinder that if multiple cinder-volume
services are configured with the same backend storage and one
cinder-volume service goes down, its volumes are stranded - the other
cinder-volume services do not take over the management of these
volumes. Details on Launchpad [1].

The workaround is to set the "host" configuration option to the same
value for all cinder-volume services, so that they all appear as one,
and use active/passive HA for cinder-volume.

The side effect is that if we use iSCSI backend with local LVM data
storage for Cinder on the HA controllers, we can only use the disk
space on one of the controllers, not all (cinder-volume service will
run on only one controller). This should not be a problem because it
is not an expected production setup with HA controller - Cinder
backend setup using local LVM data storage on controllers wouldn't
provide HA anyway. If the user wants to scale out LVM data storage
backend, they can still use the Block Storage host group. This commit
only affects HA controller.
