Subject: [PATCH] Add the hypervisors to the inventory

For use cases like ShiftOnStack the deployment may need to tweak the
hypervisor.
We did not have a way to tell the deployment how to reach the hypervisor
so this commit exposes the hypervisor Ansible instance to each host
and creates a hypervisors group in the generated inventory.
