zuul: Add nova-live-migration-ceph job

Since Ib342e2d3c395830b4667a60de7e492d3b9de2f0a the nova gate has lacked
any libvirt live migration test coverage for ceph. This change
reintroduces this via a new zuulv3 native multinode live migration job
for ceph that includes additional instance evacuation coverage.

Depends-On: https://review.opendev.org/c/openstack/devstack-plugin-ceph/+/711625
