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:
Ref T4398. This prompts users for multi-factor auth on login.
Roughly, this introduces the idea of "partial" sessions, which we haven't finished constructing yet. In practice, this means the session has made it through primary auth but not through multi-factor auth. Add a workflow for bringing a partial session up to a full one.
Test Plan:
- Used Conduit.
- Logged in as multi-factor user.
- Logged in as no-factor user.
- Tried to do non-login-things with a partial session.

- Rate limiting attempts (see TODO).
- Marking tokens used after they're used once (see TODO), maybe. I can't think of ways an attacker could capture a token without also capturing a session, offhand.
- Actually turning this on (see TODO).
- This workflow is pretty wordy. It would be nice to calm it down a bit.
- But also add more help/context to help users figure out what's going on here, I think it's not very obvious if you don't already know what "TOTP" is.
- Add admin tool to strip auth factors off an account ("Help, I lost my phone and can't log in!").
- Add admin tool to show users who don't have multi-factor auth? (so you can pester them)
- Generate QR codes to make the transfer process easier (they're fairly complicated).
- Make the "entering hi-sec" workflow actually check for auth factors and use them correctly.
- Turn this on so users can use it.
- Adding SMS as an option would be nice eventually.
- Adding "password" as an option, maybe? TOTP feels fairly good to me.

Ref T4371. Ref T4699. Fixes T3994.
Currently, we're very conservative about sending errors back to users. A concern I had about this was that mistakes could lead to email loops, massive amounts of email spam, etc. Because of this, I was pretty hesitant about replying to email with more email when I wrote this stuff.
However, this was a long time ago. We now have Message-ID deduplication, "X-Phabricator-Sent-This-Mail", generally better mail infrastructure, and rate limiting. Together, these mechanisms should reasonably prevent anything crazy (primarily, infinite email loops) from happening.
Thus:
- When we hit any processing error after receiving a mail, try to send the author a reply with details about what went wrong. These are limited to 6 per hour per address.
- Rewrite most of the errors to be more detailed and informative.
- Rewrite most of the errors in a user-facing voice ("You sent this mail..." instead of "This mail was sent..").
- Remove the redundant, less sophisticated code which does something similar in Differential.
Test Plan:

- Hit a bunch of different errors.

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.
