In microversion 2.20 we added the ablility to detach/attach volumes from a shelved(_offloaded) instance: http://git.openstack.org/cgit/openstack/nova/tree/nova/api/openstack/compute/rest_api_version_history.rst?h=stable/rocky#n177
But after we uses the cinder new attach workflow, this feature is broken, as when we delete the attachment the volume status changed to "reserved" and we cannot detach the volume with this status.
