Summary: Depends on D19173. Ref T13096. Adds an optional, disabled-by-default lock log to make it easier to figure out what is acquiring and holding locks.
Test Plan: Ran `bin/lock log --enable`, `--disable`, `--name`, etc. Saw sensible-looking output with log enabled and daemons restarted. Saw no additional output with log disabled and daemons restarted.

Summary:
Fixes T12720. Currently, old daemon records are collected based on creation date. By default, the GC collects them after 7 days.
After T12298, this can incorrectly collect hibernating daemons which are in state "wait".
In all cases, this could fail to collect daemons which are stuck in "running" for a long time for some reason. This doesn't seem to be causing any problems right now, but it makes me hesitant to do "dateCreated + not running or waiting" since that might make this become a problem, or make an existing problem with this that we just haven't bumped into worse.
Daemons always heartbeat periodically and update their rows, so `dateModified` is always fresh, so collect rows based only on modification date.
Test Plan:
- Ran daemons (`bin/phd start`).
- Waited a few minutes.
- Verified that hibernating daemons in the "wait" state had fresh timestamps.
- Verified that very old daemons still got GC'd properly.

Note that:
- The oldest daemon is <7 days old -- I had some other older rows but they got GC'd properly.
- The hibernating taskmasters (at the bottom, in state "wait") have recent/more-current `dateModified` dates than their `dateCreated` dates.

Summary:
Fixes T9494. This:
- Removes all the random GC.x.y.z config.
- Puts it all in one place that's locked and which you use `bin/garbage set-policy ...` to adjust.
- Makes every TTL-based GC configurable.
- Simplifies the code in the actual GCs.
Test Plan:
- Ran `bin/garbage collect` to collect some garbage, until it stopped collecting.
- Ran `bin/garbage set-policy ...` to shorten policy. Saw change in web UI. Ran `bin/garbage collect` again and saw it collect more garbage.
- Set policy to indefinite and saw it not collect garabge.
- Set policy to default and saw it reflected in web UI / `collect`.
- Ran `bin/phd debug trigger` and saw all GCs fire with reasonable looking queries.
- Read new docs.

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.

Summary:
We already have GC for daemon log events, but not for daemon logs themselves.
Collect old daemon logs which aren't still running.
Test Plan: Ran `phd debug garbage`, observed old logs get cleaned up. Started some daemons, re-ran garbage, made sure they stuck around.

Summary: This modularizes the rest of the GC submethods. Turned out there was nothing tricky.
Test Plan: Ran `bin/phd debug garbage` and got reasonable looking behavior and output.
