Comment 1 for bug 1810449

This may be a semi-red-herring. the service needs to be removed from the database to not confuse operators and monitoring tools, but the reasoning behind it affecting nova-api-metadata on the neutron-gateway nodes are incorrect. It turns out my issue with the ServiceTooOld message is that my cloud-archive on the neutron-gateway is stuck at newton when the charm is set to xenial-pike.
