Libvirt machine api

[enxebre]

Move libvirt machines from k8s.io into openshift.io

We are transitioning the cluster API types from k8s.io over a machine.openshift.io group.
https://github.com/openshift/cluster-api/tree/91fca585a85b163ddfd119fd09c128c9feadddca
Although this give us a necessary level of autonomy today, we aim to consolidate back with upstream once there's a release of the API stable enough

The only remaining places where sigs.k8s.io/cluster-api/ is imported is in deprecated code or in cluster object definitions.
