Summary:
Ref T4712. Thus far, it seems that most "non-standard" things can be done pretty easily in the controller. Aside from deploying, this diff had to fix a few bugs / missing implementations of stuff.

(Notably, PhabricatorAuthProviderConfig, HeraldRule, PhabricatorSlowvotePoll, and AlmanacNetwork needed to implement PhabricatorApplicationTransactionInterface, PhabricatorAuthAuthProviderPHIDType had to be added, and a rendering bug in transactions of type PhabricatorOAuth2AuthProvider had to be fixed.)

Test Plan: Almanac - looked at binding, device, network, and service view controllers and verified timeline displayed properly. Herald - looked at a rule and verified timeline. Slowvote - looked at a vote and verified timeline. Auth - looked at an auth provider (Facebook) and verified proper display of transactions within timeline.
