Enable CSIT deployments to use NFS backend

In order to support HA as well as live migration a shared storage
backend needs to be used. This patch preps the overcloud image to start
with an NFS server sharing out of /root/nfs. If csit environment file is
used then NFS parameters will be passed to the deployment, configuring
Nova and Glance to use NFS hosted by controller0.
