BZ #1056055 --  [RFE] create cinder-volumes VG backed by a loopback file

https://bugzilla.redhat.com/show_bug.cgi?id=1056055

The default behavior most customers expect for small to medium installations
is to run cinder-volume on the controller node. Packstack does this but
Foreman only allows a dedicated storage backend backed by iSCSI or RHS.
This patch deploys cinder-volume on the Nova or Neutron controller node if
cinder_backend_{iscsi,gluster} are both set to false. It will detect a VG
named cinder-volumes (whether backed by an iSCSI target or loopback device)
and share it via tgtd. The user must create the VG, which is also the case
with the cinder_backend_iscsi parameter for the LVM backend storage group. In
a sense this patch replicates functionality customers expect from packstack.
I tested it against the RHEL OSP 01.31.2014-1 puddle for both iSCSI and LVM
bakced Cinder from the controller node.

BZ #1049633 - Foreman should support VXLAN

A couple of the variables inside the compute and networker classes were missing
the 'ovs_' part of the param name.

BZ #998599 - Add options for SSL support using files or FreeIPA

https://bugzilla.redhat.com/show_bug.cgi?id=998599

If ssl and freeipa are true then certificates are obtained using
certmonger.

If ssl is true and freeipa is false then the the mysql and qpid
certificates and keys need to be passed in as arguments.

Horizon is configured to use ssl on the public interface FQDN if
ssl is true.

Secure qpid and mysql with SSL for nova, keystone, glance,
ceilometer, cinder and heat.

The following Foreman hostgroups support SSL:

Compute (Neutron)
Compute (Nova Network)
Controller (Neutron)
Controller (Nova Network)
LVM Block Storage
Neutron Networker

Fix double port 80 directives in apache.

Without this patch, apache/hoizon fails to start.
However, should be able to remove this patch once
puppet-horizon/apache better handles this case.

Host Groups may now be associated with a list of puppet classes

or just a singleton puppet class as before.  E.g., this is
now a valid definition in seeds.rb:

hostgroups = [
    {:name=>"Swift Storage Node",
     :class=>"quickstack::swift::storage"},
    {:name=>"Test Pacemaker Qpid",
     :class=>["quickstack::pacemaker::common",
              "quickstack::pacemaker::qpid"]},
