Change Ia1239069ccee39416b20959cbabad962c56693cf added support for running a libvirt daemon on the host, rather than using the nova_libvirt container. It did not cover migration of existing hosts from using a container to using a host daemon. This change adds a kolla-ansible nova-libvirt-cleanup command which may be used to clean up the nova_libvirt container, volumes and related items on hosts, once it has been disabled. The playbook assumes that compute hosts have been emptied of VMs before it runs. A future extension could support migration of existing VMs, but this is currently out of scope.
