Fixes T10783 (what little of it remains). Ref T10697.
Aphlict currently uses request paths for two different things:
- multi-tenant instancing in the Phacility cluster (each instance gets its own namespace within an Aphlict server);
- some users configure nginx and apache to do proxying or SSL termination based on the path.
Currently, these can collide.
Put a "~" before the instance name to make it unambiguous. At some point we can possibly just use a GET parameter, but I think there was some reason I didn't do that originally and this sequence of changes is disruptive enough already.
Test Plan: Saw local Aphlict unambiguously recognize "local.phacility.com" as instance "local", with a "~"-style URI.

Ref T10697. Currently, `aphlict` takes a ton of command line flags to configure exactly one admin server and exactly one client server.
I want to replace this with a config file. Additionally, I plan to support:
- arbitrary numbers of listening client ports;
- arbitrary numbers of listening admin ports;
- SSL on any port.
For now, just transform the arguments to look like they're a config file. In the future, I'll load from a config file instead.
This greater generality will allow you to do stuff like run separate HTTP and HTTPS admin ports if you really want. I don't think there's a ton of use for this, but it tends to make the code cleaner anyway and there may be some weird cross-datacneter cases for it. Certainly, we undershot with the initial design and lots of users want to terminate SSL in nginx and run only HTTP on this server.
(Some sort-of-plausible use cases are running separate HTTP and HTTPS client servers, if your Phabricator install supports both, or running multiple HTTPS servers with different certificates if you have a bizarre VPN.)

Summary:
Ref T4292. This mostly implements the locking/versioning logic for multi-master repositories. It is only active on Git SSH pathways, and doesn't actually do anything useful yet: it just does bookkeeping so far.
When we read (e.g., `git fetch`) the logic goes like this:
- Get the read lock (unique to device + repository).
- Read all the versions of the repository on every other device.
- If any node has a newer version:
- Fetch the newer version.
- Increment our version to be the same as the version we fetched.
- Release the read lock.
- Actually do the fetch.
This makes sure that any time you do a read, you always read the most recently acknowledged write. You may have to wait for an internal fetch to happen (this isn't actually implemented yet) but the operation will always work like you expect it to.
When we write (e.g., `git push`) the logic goes like this:
- Get the write lock (unique to the repository).
- Do all the read steps so we're up to date.
- Mark a write pending.
- Do the actual write.
- Bump our version and mark our write finished.
- Release the write lock.
This allows you to write to any replica. Again, you might have to wait for a fetch first, but everything will work like you expect.
There's one notable failure mode here: if the network connection between the repository node and the database fails during the write, the write lock might be released even though a write is ongoing.
The "isWriting" column protects against that, by staying locked if we lose our connection to the database. This will currently "freeze" the repository (prevent any new writes) until an administrator can sort things out, since it'd dangerous to continue doing writes (we may lose data).
(Since we won't actually acknowledge the write, I think, we could probably smooth this out a bit and make it self-healing //most// of the time: basically, have the broken node rewind itself by updating from another good node. But that's a little more complex.)
Test Plan:
- Pushed changes to a cluster-mode repository.
- Viewed web interface, saw "writing" flag and version changes.
- Pulled changes.
- Faked various failures, got sensible states.

Since the "replicating master" check needs a special permission, imposes a performance penalty, is probably very difficult to misconfigure, and likely not a big deal anyway, just drop the idea of trying to automatically detect + prevent it. We still show if it's an issue on the status page, provided we have permission to check.
When you don't have any cluster databases configured, never stop trying to connect to the default master database. We might want to do this eventually as load reduction, but just don't muddy the waters too much for now while things stabilize.

Summary:
Ref T4571. When a database goes down briefly, we fall back to replicas.
However, this fallback is slow (not good for users) and keeps sending a lot of traffic to the master (might be bad if the root cause is load-related).
Keep track of recent connections and fully degrade into "severed" mode if we see a sequence of failures over a reasonable period of time. In this mode, we send much less traffic to the master (faster for users; less load for the database).
We do send a little bit of traffic still, and if the master recovers we'll recover back into normal mode seeing several connections in a row succeed.
This is similar to what most load balancers do when pulling web servers in and out of pools.
For now, the specific numbers are:
- We do at most one health check every 3 seconds.
- If 5 checks in a row fail or succeed, we sever or un-sever the database (so it takes about 15 seconds to switch modes).
- If the database is currently marked unhealthy, we reduce timeouts and retries when connecting to it.
Test Plan:
- Configured a bad `master`.
- Browsed around for a bit, initially saw "unrechable master" errors.
- After about 15 seconds, saw "major interruption" errors instead.
- Fixed the config for `master`.
- Browsed around for a while longer.
- After about 15 seconds, things recovered.
- Used "Cluster Databases" console to keep an eye on health checks: it now shows how many recent health checks were good:

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.
