Something must have regressed in Queens because going back to Pike this still works:
usage: nova-manage db [-h] {archive_deleted_rows,ironic_flavor_migration,null_instance_uuid_scan,online_data_migrations,sync,version} ...
nova-manage db: error: too few arguments
I don't see anything obvious in the nova-manage code in Queens that changed so it must have been something in oslo.config.
