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 T6930. This application collects and displays performance samples -- roughly, things Phabricator spent some kind of resource on. It will collect samples on different types of resources and events:
- Wall time (queries, service calls, pages)
- Bytes In / Bytes Out (requests)
- Implicit requests to CSS/JS (static resources)
I've started with the simplest case (static resources), since this can be used in an immediate, straghtforward way to improve packaging (look at which individual files have the most requests recently).
There's no aggregation yet and a lot of the data isn't collected properly. Future diffs will add more dimension data (controllers, users), more event and resource types (queries, service calls, wall time), and more display options (aggregation, sorting).
