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 T4749. Ref T3265. Ref T4909. Several goals here:
- Move user destruction to the CLI to limit the power of rogue admins.
- Start consolidating all "destroy named object" scripts into a single UI, to make it easier to know how to destroy things.
- Structure object destruction so we can do a better and more automatic job of cleaning up transactions, edges, search indexes, etc.
- Log when we destroy objects so there's a record if data goes missing.
Test Plan: Used `bin/remove destroy` to destroy several users.

Summary:
This adds a system which basically keeps a record of recent actions, who took them, and how many "points" they were worth, like:
epriestley email.add 1 1233989813
epriestley email.add 1 1234298239
epriestley email.add 1 1238293981
We can use this to rate-limit actions by examining how many actions the user has taken in the past hour (i.e., their total score) and comparing that to an allowed limit.
One major thing I want to use this for is to limit the amount of error email we'll send to an email address. A big concern I have with sending more error email is that we'll end up in loops. We have some protections against this in headers already, but hard-limiting the system so it won't send more than a few errors to a particular address per hour should provide a reasonable secondary layer of protection.
This use case (where the "actor" needs to be an email address) is why the table uses strings + hashes instead of PHIDs. For external users, it might be appropriate to rate limit by cookies or IPs, too.
To prove it works, I rate limited adding email addresses. This is a very, very low-risk security thing where a user with an account can enumerate addresses (by checking if they get an error) and sort of spam/annoy people (by adding their address over and over again). Limiting them to 6 actions / hour should satisfy all real users while preventing these behaviors.
Test Plan:
This dialog is uggos but I'll fix that in a sec:
