Different hypervisor types need different configs and we should be able
to represent these differences in the openstack_user_config.yml (conf.d)
and cover the basic needs using group_vars. This change introduces five
basic hypervisor groups which we have support for today.
* ironic-compute_hosts
* kvm-compute_hosts
* lxd-compute_hosts
* qemu-compute_hosts
* powervm-compute_hosts
This gives deployers an explicit place to define hosts that will be
responsible for different compute workloads.
