Public bug reported:

request_specs and instance_mappings in nova_api DB are not removed when an instance is deleted.
In Queens they are removed when the instances are archived (https://review.openstack.org/#/c/515034/)

However, for the deployments that archived instances before running
Queens they will have request_specs and instance_mappings that are not
associated to any instance (they were already deleted).

We should have a nova-manage tool to clean these "orphan" records.
