Summary:
Ref T4571. There will be a very long path beyond this, but add a basic read-only mode. You can explicitly enable this to put Phabricator in a sort of "maintenance" mode today if you're swapping databases or something.
In the long term, we'll automatically degrade into this mode if the master database is down.
Test Plan:
- Enabled read-only mode.
- Browsed around.
- Didn't immediately see anything that was totally 100% broken.
Most stuff is 80-90% broken right now. For example:
- Stuff like submitting comments doesn't work, and gives you a confusing, unhelpful error.
- None of the UI really knows that it's read-only. EditEngine stuff should all hide itself and say "you can't add new comments while an install is in read-only mode", for example, but currently does not.

Summary:
In Mercurial 3.2 the `locate` command was deprecated in favor of `files` command. This change updates the DiffusionLowLevelMercurialPathsQuery command to conditionally use `locate` or `files` based on the version of Mercurial used.
Closes T7375
Test Plan:
My test/develop Phabricator instance is setup to run Mercurial 3.5.1.
The test procedure to verify valid file listings are being returned:
1. I navigated to `http://192.168.0.133/conduit/method/diffusion.querypaths/`
2. I populated the following fields:
- path: `"/"`
- commit: `"d721d5b57fc9ef72e47ff9d4e0c583d74a46590c"`
- callsign: `"HGTEST"`
3. I submitted request and verified that result contained all files in the repository:
```
{
"0": "README",
"1": "alpha/beta/trifle",
"2": "test/Chupacabra.cow",
"3": "test/socket.ks"
}
```
I repeated the above steps after setting up Mercurial 2.6.2, which I installed in the following manner:
1. I downloaded Mercurial 2.6.2 source and run `make local` which will only compile it to work from its own directory (`/opt/mercurial-2.6.2`)
2. I linked `/usr/local/bin/hg -> /opt/mercurial-2.6.2/hg` (there's also a `/usr/bin/hg` which is a link to `/usr/local/bin/hg`)
3. I navigated to my home directory and verify that `hg --version` returns 2.6.2.
4. I restarted phabricator services (probably unnecessary).
With the Multimeter application active
1. I verified that `/usr/local/bin/hg` referred to version 2.6
2. I ran the same conduit call from the conduit application
3. I verified that `http://192.168.0.133/multimeter/?type=2&group=label` incremented values for `bin.hg locate`.
4. I swapped out mercurial versions for 3.5.1
5. I ran the same conduit call from the conduit application
6. I verified that `http://192.168.0.133/multimeter/?type=2&group=label` incremented values for `bin.hg files`

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: Converts most all tables to be directly set via `setTable` to an ObjectBox. I think this path is more flexible design wise, as we can change the box based on children, and not just CSS. We also already do this with PropertyList, Forms, ObjectList, and Header. `setCollapsed` is added to ObjectBox to all children objects to bleed to the edges (like diffs).
Test Plan: I did a grep of `appendChild($table)` as well as searches for `PHUIObjectBoxView`, also with manual opening of hundreds of files. I'm sure I missed 5-8 places. If you just appendChild($table) nothing breaks, it just looks a little funny.

Summary: Ref T6930. We were dividing total cost by number of samples, but should more accurately divide it by the sum of the sample rates. This produces a more meaningful number.
Test Plan: Saw a more meaningful number in the UI.

Summary: Ref T6930. Only notable thing here is that I prevented non-admins from slicing down by viewing user, since it feels a little creepy to go see what pages you looked at, even though we only show which controllers you invoked. However, it feels important enough to be able to see users destorying the server with crazy requests to let admins see this data.

Summary:
Ref T6930. This application collects and displays performance samples -- roughly, things Phabricator spent some kind of resource on. It will collect samples on different types of resources and events:
- Wall time (queries, service calls, pages)
- Bytes In / Bytes Out (requests)
- Implicit requests to CSS/JS (static resources)
I've started with the simplest case (static resources), since this can be used in an immediate, straghtforward way to improve packaging (look at which individual files have the most requests recently).
There's no aggregation yet and a lot of the data isn't collected properly. Future diffs will add more dimension data (controllers, users), more event and resource types (queries, service calls, wall time), and more display options (aggregation, sorting).
