Summary:
Phabricator generates a bunch of data that we don't need to keep around forever,
add a GC daemon to get rid of it with some basic configuration options.
This needs a couple more diffs to get some of the details but I think this is a
reasonable start.
I also fixed a couple of UI things related to this, e.g. the daemon logs page
going crazy when a daemon gets stuck in a loop and dumps tons of data to stdout.
Test Plan:
- Ran gc daemon in 'phd debug' mode and saw it delete stuff, then sleep once
it had cleaned everything up.
- Mucked around with TTLs and verified they work correctly.
- Viewed gc'd transcripts in the web interface and made sure they displayed
okay.
- Viewed daemon logs before/after garbage collection.
- Running some run-at / run-for tests now, I'll update if the daemon doesn't
shut off in ~10-15 minutes. :P
