Summary:
When previously known commits have been destroyed in a Mercurial repository, Phabricator does not end up marking the commits as unreachable. This results in daemon tasks which continuously fail and retry.
This updates `PhabricatorRepositoryDiscoveryEngine` and `PhabricatorManagementRepositoryMarkReachableWorkflow` to include support of marking commits as unreachable for Mercurial repositories.
The `PhabricatorMercurialGraphStream` also needed updated to support a stream with no starting commit.

1. I set up a hosted Mercurial repository.
2. I removed the head commit from the on-disk repository state.
3. I attempted to load the repository page and saw an exception due to a missing commit.
4. I went to `/manage` for the repository and scheduled an update of the repository.
5. After an updated performed, I went to the repository main page and saw there was no exception and the history view properly did not have the commit I had removed.
6. I checked the phd logs and verified there were no exceptions related to the repository.
7. I ran the `./bin/repository mark-reachable` command on the Mercurial repository and it reported that it marked the commit as unreachable.
8. I pushed the same commit back upstream and verified that the commit was found and displayed in the history view of the repository page and `mark-unreachable` did not identify it as being unreachable.

Summary:
Ref T13600. When migrating observed repositories between cluster services, impact can be better controlled by fetching a copy of the repository on the target host before clusterizing it.
In particular, in the Phacility cluster, migrations are generally from one shared shard to one dedicated shard. It's helpful to perform these migrations synchronously without waiting for the cluster to sync in the background (helpful in the sense that there are fewer steps and fewer commands to run).
This supports an "--observe" mode to the internal "bin/services load-repository" workflow, which transfers repository data by refetching it from the remote rather than by getting it from the older host. This fetch occurs before cluster configuration is adjusted.
Test Plan: Ran locally as a sanity check, will apply in production.

For PHI1165, which ran into a race with message parsing, I originally believed we needed to separate this logic and lock + yield to avoid the race. D20462 provides what is probably a better approach for avoiding the race.
Still, I think separating these "update related revisions" and "updated related tasks" chunks into separate workers is a net improvement. There may still be some value in doing lock + yield in the future to deal with other issues, and when we occasionally run into problems with pulling a diff out of the repository to update the revision (usually because the diff is too big) this isolates the problem better and allows the commit to import.
I think the only thing to watch out for here is that Herald may now run before the revision and commit are attached to one another. This is fine for all current Herald rules, we just need to be mindful in implementing new rules.

Summary:
Ref T13216. See PHI943. If autoscale lightning strikes all your servers at once and destroys them, the path to recovery can be unclear. You're "supposed" to:
- demote all the devices;
- disable the bindings;
- bind the new servers;
- put whatever working copies you can scrape up back on disk;
- promote one of the new servers.
However, the documentation is a bit misleading (it was sort of written with "you lost one or two devices" in mind, not "you lost every device") and demote-before-disable is unnecessary and slightly risky if servers come back online. There's also a missing guardrail before the promote step which lets you accidentally skip the demotion step and end up in a confusing state. Instead:
- Add a guard rail: when you try to promote a new server, warn if inactive devices still have versions and tell the user to demote them.
- Allow demotion of inactive devices: the order "disable, demote" is safer and more intuitive than "demote, disable" and there's no reason to require the unintuitive order.
- Make the "cluster already has leaders" message more clear.
- Make the documentation more clear.
Test Plan:
- Bound a repository to two devices.
- Wrote to A to make it a leader, then disabled it (simulating a lightning strike).
- Tried to promote B. Got a new, useful error ("demote A first").

However, installs may not do this for whatever reason, and we aren't as clear as we could be in warning about clusterizing directly into a multi-device cluster.
Roughly, when you do this, we end up believing that working copies exist on several different devices, but have no information about which copy or copies are up to date. //Usually// they all were already synchronized and are all up to date, but we can't make this assumption safely without risking data.
Instead, we err on the side of caution, and require a human to tell us which copy we should consider to be up-to-date, using `bin/repository thaw --promote`.
Test Plan:
```
$ ./bin/repository clusterize rLOCKS --service repos001.phacility.net
Service "repos001.phacility.net" is actively bound to more than one device
(local002.local, local001.phacility.net).
If you clusterize a repository onto this service it will be unclear which
devices have up-to-date copies of the repository. This leader/follower
ambiguity will freeze the repository. You may need to manually promote a
device to unfreeze it. See "Ambiguous Leaders" in the documentation for
discussion.

Ref T4292. Currently, we hold one big lock around the whole `bin/repository update` workflow.
When running multiple daemons on different hosts, this lock can end up being contentious. In particular, we'll hold it during `git fetch` on every host globally, even though it's only useful to hold it locally per-device (that is, it's fine/good/expected if `repo001` and `repo002` happen to be fetching from a repository they are observing at the same time).
Instead, split it into two locks:
- One lock is scoped to the current device, and held during pull (usually `git fetch`). This just keeps multiple daemons accidentally running on the same host from making a mess when trying to initialize or update a working copy.
- One lock is scoped globally, and held during discovery. This makes sure daemons on different hosts don't step on each other when updating the database.
If we fail to acquire either lock, assume some other process is legitimately doing the work and bail more quietly instead of fataling. In approximately 100% of cases where users have hit this lock contention, that was the case: some other daemon was running somewhere doing the work and the error didn't actually represent an issue.
If there's an actual problem, we still raise a diagnostically useful message if you run `bin/repository update` manually, so there are still tools to figure out that something is hung or whatever.
Test Plan:
- Ran `bin/repository update`, `pull`, `discover`.
- Added `sleep(5)`, forced processes to contend, got lock exceptions and graceful exit with diagnostic message.

Summary:
Fixes T10940. Two issues currently:
First, `PullLocal` deamon refuses to update non-cluster repositories on cluster devices. However, this is surprising/confusing/bad because as soon as you enroll a repository host in the cluster, most of the repositories on it stop working until you `clusterize` them. This is especially confusing because the documentation gives you a very nice, gradual walkthrough about going through things slowly and being able to check your work at every step, but we really drop you off a bit of a cliff here. The workflow implied by the documentation is a desirable one.
This operation is generally only unsafe/problematic if the daemon would be creating a //new// working copy. If a working copy already exists, we can reasonably guess that it's almost certainly because you've enrolled a previously un-clustered host into a new cluster. This allows the nice, gradual workflow the documentation describes to proceed as expected, without any weird surprises.
Instead of refusing to update these repositories, only refuse to update them if updating would create a new working copy. This should make transitioning much smoother without any meaningful reduction in safety.
Second, the lower-level `bin/repository update`, `refs`, `mirror`, etc., commands don't apply this same check. However, these commands are potentially just as dangerous. Use the same code to do a similar check there, making sure we only operate on repositories that are either expected to be on the current device, or which already exist here.
Test Plan:
- Ran `bin/phd debug pull`, saw diagnostic information choose to update most repositories (including some non-cluster repositories) but properly skip non-cluster repositories that do not exist locally.
- Ran `bin/repository update`, etc., saw the command apply consistent rules to the rules applied by `PullLocal` and refuse to update non-local repositories it would need to create.

Summary:
Ref T10748. This migrates and swaps mirroring to `PhabricatorRepositoryURI`, obsoleting `PhabricatorRepositoryMirror`.
This prevents you from editing, adding or disabling mirrors unless you know a secret URI (until the UI cuts over fully), but existing mirroring is not affected.
Test Plan:
- Added a mirroring URI to an old repository.
- Verified it worked with `bin/repository mirror`.
- Migrated forward.
- Verified it still worked with `bin/repository mirror`.
- Wow, mirroring: https://github.com/epriestley/locktopia-mirror

Summary:
Ref T10748. In D14250#158181, I accepted this conditional on removing it once Conduit could handle it.
Conduit can now handle it, or at least will be able to as soon as T10748 cuts over.
Test Plan: Grepped for `repository edit`.

Summary:
Ref T4039. Long ago these were more freely editable and there were some security concerns around creating a repository, then setting its local path to point somewhere it shouldn't.
Local paths are no longer editable so there's no real reason we need to provide a uniqueness guarantee anymore, but you could still make a mistake with `bin/repository move-paths` by accident, and it's a little cleaner to pull them out into their own column with a key.
(We still don't -- and, largely can't -- guarantee that two paths aren't //equivalent// since one might be symlinked to the other, or symlinked only on some hosts, or whatever, but the primary value here is as a sanity check that you aren't goofing things up and pointing a bunch of repositories at the same working copy by mistake.)
Test Plan:
- Ran migrations.
- Grepped for `local-path`.
- Listed and moved paths with `bin/repository`.
- Created a new repository, verified its local path populated correctly.

Summary: Ref T4292. This provides at least some sort of hint about how to set up cluster repositories.
Test Plan:
- Read documentation.
- Ran `bin/repository clusterize` to add + remove clusters.

Summary: This gets over-escaped instead of bolded right now, but I only ever hit it when exporting/importing and never both cleaning it up.
Test Plan: Ran `bin/repository move-paths`, saw bolded "Move" instead of ANSI escape sequences.

Summary:
Ref T4292. When the daemons make a query for repository information, we need to make sure the working copy on disk is up to date before we serve the response, since we might not have the inforamtion we need to respond otherwise.
We do this automatically for almost all Diffusion methods, but this particular method is a little unusual and does not get this check for free. Add this check.
Test Plan:
- Made this code throw.
- Ran `bin/repository reparse --message ...`, saw the code get hit.
- Ran `bin/repository lookup-user ...`, saw this code get hit.
- Made this code not throw.

Summary:
Ref T10751. Add support tooling for manually prying your way out of trouble if disaster strikes.
Refine documentation, try to refer to devices as "devices" more consistently instead of sometimes calling them "nodes".
Test Plan: Promoted and demoted repository devices with `bin/repository thaw`.
