Track daemon unique IDs in Phabricator daemon logs

Summary:
Ref T7352. We were previously identifying things by `<daemonClass, overseerPID, startTime>` but that's not unique in a world where one overseer can run multiple daemons.

We already have an internal "daemonID", it just doesn't get written into the DB right now.

Start writing it, then use it to clean up `phd status`.

Test Plan: Ran `phd status`, got more accurate/useful output than previously.
