Oban 2.0.0 migration disabled all job pruning
!2674 (merged) updated oban 2.0.0, during migration it was brought up that the previous method for pruning was now gone. We discussed adopting another method introduced in 2.0.0, but for some reason the MR was merged without it being implemented. This is a big deal because right now we store the whole activity payload in every federation job for every host (optimizing this was talked about on irc and iirc @href said he was working on it), so without pruning it will bloat up the DB very fast. patch.cx was updated to recent develop only yesterday and already has 123mb in oban_jobs
table. See https://github.com/sorentwo/oban#pruning-historic-jobs for how to enable pruning
