Expand description

Slugs of the exercise services this API can serve: exactly those declaring supports_native_client.

Reads the exercise_service_info cache, which service-info-fetcher refreshes about once a minute; fetching live would fan every request out to every exercise service. An empty set therefore usually means that fetcher is down or cold, which the client sees only as empty course and exercise lists — hence the warning.
