Fix PostgreSQL load when linking in announcements (#13250) * Fix PostgreSQL load when linking in announcements Fixes #13245 by caching status lookups Since statuses are supposed to be known already and we only need their URLs and a few other things, caching them should be fine. Since it's only used by announcements so far, there won't be much statuses to cache. * Perform status lookup when saving announcements, not when rendering them * Change EntityCache#status to fetch URLs instead of looking into the database * Move announcement link lookup to publishing worker * Address issues pointed out during review 2020-04-05 10:51:22 +00:00			`class AddStatusIdsToAnnouncements < ActiveRecord::Migration[5.2]`
