Summary:
Ref T7811. Fixes two minor issues I observed in the cluster:
- Sometimes APC doesn't give us key names. Not sure exactly what's up here, but we can do a better job with this.
- The `%` in `25%` actually needs more escaping, since it's interpreted by both `pht()` (immediately) and `console_format()` (later).
Test Plan:
- First one is just from an error log, not sure how to repro offhand.
- Ran `bin/phd help start` for the second one.

Summary:
Fixes T7352. This reduces the memory footprint for instances by combining these two similar daemons into one daemon which handles the responsibilities of both.
The fit isn't 100% perfect here but it's pretty close, and the GC daemon is fairly trivial.
Test Plan:
- Adjusted all the numbers to small numbers (5 second sleep, 120 second GC length).
- Added a ton of logging.
- Started trigger daemon.
- Saw it run a GC cycle.
- Saw it reschedule another cycle after 120 seconds (adjusted down from 4 hours).
- Reverted all the logging/small numbers.
- Ran `bin/phd start`, saw stable trigger daemon running.
- Grepped for removed daemon class name.

Summary:
Fixes T5154. Currently, "phd stop" terminates daemons relatively abruptly (and other things do too, like killing them). This can leave them with long leases that won't expire any time soon. Normally this isn't a big deal, since it just means an email or an import takes a bit longer (often 2 hours, but up to 24 hours) to run. However:
- We've increased default lease durations a lot fairly recently -- the 2 hours used to be 15 minutes.
- Harbormaster and Drydock add new types of tasks which are more dependent on other tasks, so waiting 2 hours for something to free up can hold up more stuff in queue.
When `phd start` is run, we can be confident (at least, in normal circumstances) that leases are safe to free, since we do a check. This undoes any damage done by abrupt stops in "phd stop" or by users or systems killing stuff.
(It would be nice to make "phd stop" more graceful at some point, but we always have to deal with abrupt termination in some cases no matter how gentle "phd stop" is.)
One sort-of-questionable thing here is that we don't distinguish between tasks which had an active lease and tasks which had been released, since the system itself does not make a distiction. So, for example, if you have a task that retries 5 times and waits an hour between retries, you'll get a retry on every `phd start` now, and could exhaust them all in a few minutes if you cycle `phd start` aggressively. I think this is OK. In the future, we could try to distinguish between these types of tasks, and only free the ones with active leases.
Test Plan:
- Used `phd start` normally, saw it free leases.
- Used `phd start`, killed it real quick so no taskmasters spawned, ran it again an saw no leases freed.
- Used `phd start --keep-leases`.

Summary:
See <http://github.com/facebook/phabricator/issues/487>. By default, we perform a write in this query to moved daemons to "dead" status after a timeout. This is normally reasonable, but after D7964 we do a setup check against the daemons, which means this query is invoked very early in the stack, before we have a write guard.
Since doing this write unconditionally is unnecessarily, surprising, and overly ambitious, make the write conditional and do not attempt to perform it from the setup check.
(We could also move this to a GC/cron sort of thing eventually, maybe -- it's a bit awkward here, but we don't have other infrastructure which is a great fit right now.)
