Comment 4 for bug 1646255

Looks like https://github.com/openstack/nova/blob/13.1.2/nova/compute/manager.py#L6513 doesn't help on remove the compute node record. It only delete the compute node which hypervisor didn't know.

Probably we have same problem, when the compute is down, then user remove the service records, then still no-one can remove the compute node record.
