Updated openstack-ansible-modules to latest upstream
Fixed haproxy-server role so that vip is determined and created correctly
Removed network configuration for tenant network from neutron roles

This repository and playbooks are moving towards a model where they don't
try and interfere with basic system setup. You simply setup all network
interfaces correctly outside of this playbook in your provisioning system
(foreman, cobbler, razor, etc) and the playbook simply takes the information
it needs to deploy Openstack.
Make nova-server/compute role ensure that libvirt is installed and running
Change pacemaker-cluster role to default the members of the cluster to the hosts in the current play
Removed networking configuration file that is no longer used
Remove the need to set the local_ip of network and compute nodes

Now that networking setup for the tenant network is no longer
the responsibility of these playbooks/roles, all we need to know
is what interface you are using on each node for tenant networks.
We can use ansible facts to determine the ip address of that
interface to populate configuration files
