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 T5791. This edge table grows 2+X faster than the corresponding mail table depending on usage. Ergo, lets make sure to clean that up too in the delete code.
Test Plan: careful thought

Summary: Ref T4368. We don't currently GC these tables, and the sent mail table is one of the largest on `secure.phabricator.com`. There's no value in retaining this information indefinitely. Instead, retain it for 90 days, which should be plenty of time to debug/diagnose any issues.
Test Plan: Ran `phd debug garbage`, saw it clean up a reasonable amount of data from these tables.
