>From the logs I see cinder.auth_type = None so the [cinder] section of
the nova configuration is not configured for a service user to act on
behalf of the user to detach and delete the volume. With
reclaim_instance_interval>0 the periodic task in the compute service
will delete the server and the volume but doesn't have the user token so
you must configure nova to have admin rights to work with cinder on the
user's behalf. For example:

https://review.opendev.org/#/c/685488/

I'm going to mark this as invalid since it's a misconfiguration, though
arguably we should update the documentation for the
reclaim_instance_interval option to mention needing to configure cinder
to properly clean up volumes when the server is deleted.
