adfe84ffce Add HarbormasterRunnerWorker, for running CI tests
Summary:
This is very preliminary and doesn't actually do anything useful. In theory, it uses Drydock to check out a working copy and run tests. In practice, it's not actually capable of running any of our tests (because of complicated interdependency stuff), but does check out a working copy and //try// to run tests there.

Adds various sorts of utility methods to various things as well.

Test Plan: Ran `reparse.php --harbormaster --trace <commit>`, observed attempt to run tests via Drydock.

cce5ebebe9 Improve Drydock's ability to allocate leases correctly
Summary:
Right now, Drydock gives out multiple leases to the same working copy and gives out leases to working copies with repository "P" in them when the user requested some other repository.

Add two callbacks:

  - `canAllocateLease()` - allows a blueprint to reject a lease on a resource because of a fundamental incompatibility, like "it's a working copy with Phabricator in it, but the lease wants a working copy with Javelin in it".
  - `shouldAllocateLease()` - allows a blueprint to reject a lease on a resource because of resource limits, like "only one active lease can own a working copy at a time".

Also cleaned up various other things.

Test Plan:
After implementing the callbacks, Drydock has the correct behavior:

  - It gives multiple leases on `localhost`, but only one lease per working-copy resource.
  - It does not grant leases on resources with repository X to requests for repository Y.

Ran `bin/drydock lease --type working-copy --repositoryID 12` and similar repeatedly and verified results in the web console.

150f711cc8 Make drydock case sensitive in attribute parsing
Summary: See D4047. Get rid of this strtolower() junk.

Test Plan:
```
$ /bin/drydock lease --type working-copy --attributes repositoryID=12
Acquired Lease 66
```

b04114f95c Allow Drydock to allocate (very basic) working copy resources
Summary: This is missing a lot of features, but technically allows working copy allocation.

Test Plan: Ran `drydock lease --type working-copy --attributes repositoryID=12`, got a working copy of Phabricator allocated on disk.

7e0ce08154 Make various Drydock CLI/Allocator improvements
Summary:
  - Remove EC2, RemoteHost, Application, etc., blueprints for now. They're very proof-of-concept and Blueprints are getting API changes I don't want to bother propagating for now. Leave the abstract base class and the LocalHost blueprint. I'll restore the more complicated ones once better foundations are in place.
  - Remove the Allocate controller from the web UI. The original vision here was that you'd manually allocate resources in some cases, but it no longer makes sense to do so as all allocations come from leases now. This simplifies allocations and makes the rule for when we can clean up resources clear-cut (if a resource has no more active leases, it can be cleaned up). Instead, we'll build resources like the localhost and remote hosts lazily, when leases come in for them.
  - Add some configuration to manage the localhost blueprint.
  - Refactor `canAllocateResources()` into `isEnabled()` (for config checks) and `canAllocateMoreResources()` (for quota checks, e.g. too many resources are allocated already).
  - Juggle some signatures to align better with a world where blueprints generally do allocate.
  - Add some more logging and error handling.
  - Fix an issue with log ordering.

Test Plan: Allocated some localhost leases.

ef85f49adc Delete license headers from files
Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).

We are removing the headers for these reasons:

- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.

This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).

Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.

89b37f0357 Make various Drydock improvements
Summary:
Tightens up a bunch of stuff:

  - In `drydock lease`, pull and print logs so the user can see what's happening.
  - Remove `DrydockAllocator`, which was a dumb class that did nothing. Move the tiny amount of logic it held directly to `DrydockLease`.
  - Move `resourceType` from worker task metadata directly to `DrydockLease`. Other things (like the web UI) can be more informative with this information available.
  - Pass leases to `allocateResource()`. We always allocate in response to a lease activation request, and the lease often has vital information. This also allows us to associate logs with leases correctly.

Test Plan: Ran `drydock lease --type host` and saw it perform a host allocation in EC2.

f0fdcf1a51 Undumb the Drydock resource allocator pipeline
Summary:
This was the major goal of D3859/D3855, and to a lesser degree D3854/D3852.

As Drydock is allocating a resource, it may need to allocate other resources first. For example, if it's allocating a working copy, it may need to allocate a host first.

Currently, we have the process basically queue up the allocation (insert a task into the queue) and sleep() until it finishes. This is problematic for a bunch of reasons, but the major one is that if allocation takes more resources (host, port, machine, DNS) than you have daemons, they could all end up sleeping and waiting for some other daemon to do their work. This is really stupid. Even if you only take up some of them, you're spending slots sleeping when you could be doing useful work.

To partially get around this and make the CLI experience less dumb, there's this goofy `synchronous` flag that gets passed around everywhere and pushes the workflow through a pile of special cases. Basically the `synchronous` flag causes us to do everything in-process. But this is dumb too because we'd rather do things in parallel if we can, and we have to have a lot of special case code to make it work at all.

Get rid of all of this. Instead of sleep()ing, try to work on the tasks that need to be worked on. If another daemon grabbed them already that's fine, but in the worst case we just gracefully degrade and do everything in process. So we get the best of both worlds: if we have parallelizable tasks and free daemons, things will execute in parallel. If we have nonparallelizable tasks or no free daemons, things will execute in process.

Test Plan: Ran `drydock_control.php --trace` and saw it perform cascading allocations without sleeping or special casing.

6cc196a2e5 Move files in Phabricator one level up
Summary:
- `kill_init.php` said "Moving 1000 files" - I hope that this is not some limit in `FileFinder`.
- [src/infrastructure/celerity] `git mv utils.php map.php; git mv api/utils.php api.php`
- Comment `phutil_libraries` in `.arcconfig` and run `arc liberate`.

NOTE: `arc diff` timed out so I'm pushing it without review.

Test Plan:
/D1234
Browsed around, especially in `applications/repository/worker/commitchangeparser` and `applications/` in general.
