By default, the Kibana dashboard is now exposed on the public network.
To change this configuration, the deployer will have to assign the
'kibana' role to another network using Fuel netwowrk templates.
This change makes sure that Pacemaker and HAProxy are reconfigured
on the nodes that are already deployed when the environment is scaled
up. We use the 'update_required' stanza to enforce that the nodes
already deployed are updated in the same run than the new nodes. The
'reexecute_on' stanza doesn't guarantee that.
- Add firewall rules for corosync communication
- Use dedicated cluster.pp manifest to allow the deployment of coexistant
clusters for LMA plugins
