A request to https://musicbrainz.org/statistics/timeline/type-data can take at least 17s, which is absurdly long. We should look into caching the calls/responses to make this more sensible.

bitmap commented: "The CATALYST_DEBUG view can probably tell you where time is being spent.  The get_all calls should already be cached AFAIK, so perhaps it's get_types_for_timeline.  Then anything slow should be cached in redis.  We could probably even cache the whole response."
