Add observability for self-managed metadata database usage
We already have some visibility from Determine the type of container registry to dri... (#204839 - closed), so we can extend that to flag the metadata DB as a feature when it's enabled (in the container_registry_features
header returned by the registry). Then, we can have this exposed in service ping, and get a view of how many instances are relying on the DB.
