Summary:
Ref T4571. If we fail to connect to the master, automatically try to degrade into a temporary read-only mode ("UNREACHABLE") for the remainder of the request, if possible.
If the request was something like "load the homepage", that'll work fine. If it was something like "submit a comment", there's nothing we can do and we just have to fail.
Detecting this condition imposes a performance penalty: every request checks the connection and gives the database a long time to respond, since we don't want to drop writes unless we have to. So the degraded mode works, but it's really slow, and may perpetuate the problem if the root issue is load-related.
This lays the groundwork for improving this case by degrading futher into a "SEVERED" mode which will persist across requests. In the future, if several requests in a short period of time fail, we'll sever the database host and refuse to try to connect to it for a little while, connecting directly to replicas instead (basically, we're "health checking" the master, like a load balancer would health check a web application server). This will give us a better (much faster) degraded mode in a major service disruption, and reduce load on the master if the root cause is load-related, giving it a better chance of recovering on its own.
Test Plan:
- Disabled master in config by changing the host/username, got degraded automatically to UNREACAHBLE mode immediately.
- Faked full SEVERED mode, requests hit replicas and put me in the mode properly.
- Made stuff work, hit some good pages.
- Hit some non-cluster pages.

Ref T10538. Ref T10537. This creates PHIDs which represent GitHub users, and uses them as the actors for synchronized comments.
I've just made them Doorkeeper objects. There are three major kinds of objects they //could// possibly be:
- Nuance requestor objects.
- External account objects.
- Doorkeeper objects.
I don't think we actually need distinct nuance requestor objects. These don't really do anything right now, and were originally created before Doorkeeper. I think Doorkeeper is a superset of nuance requestor functionality, and better developed and more flexible.
Likewise, doorkeeper objects are much more flexible than external account objects, and it's nice to imagine that we can import from Twootfeed or whatever without needing to build full OAuth for it. I also like less stuff touching auth code, when possible.
Making these separate from external accounts does make it a bit harder to reconcile external users with internal users, but I think that's OK, and that it's generally desirable to show the real source of a piece of content. That is, if I wrote a comment on GitHub but also have a Phabricator account, I think it's good to show "epriestley (GitHub)" (the GitHub user) as the author, not "epriestley" (the Phabricator user). I think this is generally less confusing overall, and we can add more linkage later to make it clearer.

Fixes T10234. This is a more thorough fix.
Root issue is that some time around D13589, we started hitting an object cache for `loadCustomInlineRules()`, but didn't adjust the code to account for that.
So if a page created multiple similar engines, we'd return the same `$rule` object for multiple engines, call `setEngine()` on it with different engines, and then possibly try to render using an already-expired engine the second time through.
Instead, create a separate `$rule` object for each separate `$engine`.
Test Plan:
Repro is something like this:
- Create a custominlinerule which uses an engine.
- Purge the remarkup cache.
- Load a page which uses the rule in two engines (e.g., in a revision description, and also in an inline comment).
- Before change: second one could fatal. After change: clean load.

This doesn't do much yet and may change, but my thinking is:
- I'm putting these on-object instead of on edges because I think we want to actively change the UI for them (e.g., clearly call out that the object is bridged) but don't want every page to need to do extra queries in the common case where zero bridged objects exist anywhere in the system.
- I'm making these one-to-one, more or less: an issue can't be bridged to a bunch of tasks, nor can a bunch of tasks be bridged to a single issue. Pretty sure this makes sense? I can't come up with any reasonable, realistic cases where you want a single GitHub issue to publish to multiple different tasks in Maniphest.
- Technically, one type of each bridgable object could be bridged, but I expect this to never actually occur. Hopefully.
