Summary:
//(this diff used to be about applying policies to blueprints)//
This restructures Drydock so that blueprints are instances in the DB, with an associated implementation class. Thus resources now have a `blueprintPHID` instead of `blueprintClass` and DrydockBlueprint becomes a DAO. The old DrydockBlueprint is renamed to DrydockBlueprintImplementation, and the DrydockBlueprint DAO has a `blueprintClass` column on it.
This now just implements CAN_VIEW and CAN_EDIT policies for blueprints, although they are probably not enforced in all of the places they could be.
Test Plan: Used the `create-resource` and `lease` commands. Closed resources and leases in the UI. Clicked around the new and old lists to make sure everything is still working.

If a PhabricatorActionItem is a workflow and there is no user OR the user is logged out, we used this objectURI to construct a log in URI.
Potentially added some undesirable behavior to aggressively setUser (and later setObjectURI) from within the List on Actions... This should be okay-ish unless there was a vision of actions having different user objects associated with them. I think this is a safe assumption.

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.

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).

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.

Summary:
I'm trying to make progress on the policy/visibility stuff since it's a blocker for Wikimedia.
First, I want to improve Projects so they can serve as policy groups (e.g., an object can have a visibility policy like "Visible to: members of project 'security'"). However, doing this without breaking anything or snowballing into a bigger change is a bit awkward because Projects are name-ordered and we have a Conduit API which does offset paging. Rather than breaking or rewriting this stuff, I want to just continue offset paging them for now.
So I'm going to make PhabricatorPolicyQuery extend PhabricatorOffsetPagedQuery, but can't currently since the `executeWithPager` methods would clash. These methods do different things anyway and are probably better with different names.
This also generally improves the names of these classes, since cursors are not necessarily IDs (in the feed case, they're "chronlogicalKeys", for example). I did leave some of the interals as "ID" since calling them "Cursor"s (e.g., `setAfterCursor()`) seemed a little wrong -- it should maybe be `setAfterCursorPosition()`. These APIs have very limited use and can easily be made more consistent later.

Summary:
Rough cut of Drydock. This is very basic and doesn't do much of use yet (it
//does// allocate EC2 machines as host resources and expose interfaces to them),
but I think the overall structure is more or less reasonable.
== Interfaces
Vision: Applications interact with Drydock resources through DrydockInterfaces,
like **command**, **filesystem** and **httpd** interfaces. Each interface allows
applications to perform some kind of operation on the resource, like executing
commands, reading/writing files, or configuring a web server. Interfaces have a
concrete, specific API:
// Filesystem Interface
$fs = $lease->getInterface('filesystem'); // Constants, some day?
$fs->writeFile('index.html', 'hello world!');
// Command Interface
$cmd = $lease->getInterface('command');
echo $cmd->execx('uptime');
// HTTPD Interface
$httpd = $lease->getInterface('httpd');
$httpd->restart();
Interfaces are mostly just stock, although installs might add new interfaces if
they expose different ways to interact with resources (for instance, a resource
might want to expose a new 'MongoDB' interface or whatever).
Currently: We have like part of a command interface.
== Leases
Vision: Leases keep track of which resources are in use, and what they're being
used for. They allow us to know when we need to allocate more resources (too
many sandcastles on the existing hosts, e.g.) and when we can release resources
(because they are no longer being used). They also give applications something
to hold while resources are being allocated.
// EXAMPLE: How this should work some day.
$allocator = new DrydockAllocator();
$allocator->setResourceType('sandcastle');
$allocator->setAttributes(
array(
'diffID' => $diff->getID(),
));
$lease = $allocator->allocate();
$diff->setSandcastleLeaseID($lease->getID());
// ...
if ($lease->getStatus() == DrydockLeaseStatus::STATUS_ACTIVE) {
$sandcastle_link = $lease->getInterface('httpd')->getURI('/');
} else {
$sandcastle_link = 'Still building your sandcastle...';
}
echo "Sandcastle for this diff: ".$sandcastle_link;
// EXAMPLE: How this actually works now.
$allocator = new DrydockAllocator();
$allocator->setResourceType('host');
// NOTE: Allocation is currently synchronous but will be task-driven soon.
$lease = $allocator->allocate();
Leases are completely stock, installs will not define new lease types.
Currently: Leases exist and work but are very very basic.
== Resources
Vision: Resources represent some actual thing we've put somewhere, whether it's
a host, a block of storage, a webroot, or whatever else. Applications interact
through resources by acquiring leases to them, and then getting interfaces
through these leases. The lease acquisition process has a side effect of
allocating new resources if a lease can't be acquired on existing resources
(e.g., the application wants storage but all storage resources are full) and
things are configured to autoscale.
Resources may themselves acquire leases in order to allocate. For instance, a
storage resource might first acquire a lease to a host resource. A 'test
scaffold' resource might lease a storage resource and a mysql resource.
Not all resources are auto-allocate: the entry-level version of Drydock is that
you manually allocate a couple boxes and configure them through the web console.
Then, e.g., 'storage' / 'webroot' resources allocate on top of them, but the
host pool itself does not autoscale.
Resources are completely stock, they are abstract shells representing any
arbitrary thing.
Currently: Resource exist ('host' only) but are very very basic.
== Blueprints
Vision: Blueprints contain instructions for building interfaces to, (possibly)
allocating, updating, managing, and destroying a specific type of resource in a
specific location. One way to think of them is that they are scripts for
creating and deleting resources. For example, the LocalHost, RemoteHost and
EC2Host blueprints can all manage 'host' resources.
Eventually, we will support more types of resources (storage, webroot,
sandcastle, test scaffold, phacility deployment) and more providers for resource
types, some of which will be in the Phabricator mainline and some of which will
be custom.
Blueprints are very custom and specific to application types, so installs will
define new blueprints if they are making significant use of Drydock.
Currently: They exist but have few capabilities. The stock blueprints do nearly
nothing useful. There is a technically functional blueprint for host allocation
in EC2.
== Allocator
This is just the actual code to execute the lease acquisition process.
Test Plan: Ran "drydock_control.php" script, it allocated a machine in EC2,
acquired a lease on it, interfaced with it, and then released the lease. Ran it
again, got a fresh lease on the existing resource.
