Add initial config to support deployments on VMs

* Add initial version of PDF and IDF that
will be consumed by the hardware provisioner used in
Kuberef to bring up libvirt VMs (for now 2 VMs for dev purposes).
* Add deploy_on_vms.sh script to deploy Kuberef on VMs
* Add new functions referenced by the deploy_on_vms.sh
script - these can be merged with existing functions
* Modify some of te BMRA templates to accomodate new changes.

This has been tested on Ubuntu 18.04 baremetal server.
