Daemons - introduce PhabricatorWorkerArchiveTaskQuery

Summary: Ref T5402. This cleans up some code and sets us up to use this sort of data more easily later.

Test Plan: viewed the daemon console from the web and the log of a specific archived daemon. both looked good. for other callsites looked really, really carefully.
