Add create vm script and foreman config

Add a script to create a KVM machine and install foreman in it.
This is the beginning of the OpenSteak installation mecanism.
It is very similare as what is done in the Foreman/Quickstack approach
with small differences:
 - Ubuntu as base OS (instead of CentOS)
 - Foreman v1.8 (instead of 1.7.5
 - KVM (libvirt) virtual machine (instead of Vagrant)
 - Only python/bash scripts to manage all the stuff (instead of
   Khaleesi/Ansible/Astaport playbooks)
