Introduce HarbormasterBuildTarget to snapshot build steps through a build

Summary: This implements build targets as outlined in D7582.  Build targets represent an instance of a build step particular to the build.  Logs and artifacts have been adjusted to attach to build targets instead of build / build step pairs.

Test Plan: Ran builds and clicked around the interface.  Everything seemed to work.

Implement support for leasing from Drydock hosts in Harbormaster

Summary:
This adds LeaseHostBuildStepImplementation for getting leases on hosts in Drydock via Harbormaster.  It stores the resulting lease in an artifact.

There is also a few bug fixes as well.

Test Plan: Created a build plan with a "Lease Host" build step.  Ran the build plan and saw the build pass and the artifact in the database.

Test Plan:
Created a build plan with a "Lease Host" step and a "Run Command" step.  Configured the "Run Command" step to use the artifact from the "Lease Host" step.

Make "Edit Build Plan" more resiliant so old build configurations can be deleted

Summary: Currently the "Edit Build Plan" page crashes if there are any build steps with invalid implementations (because the implementation class has been removed or renamed).  This updates the Edit Build Plan page so that steps with invalid implementations can be deleted.

Test Plan: Looked at a build plan with invalid configurations and deleted it's steps.

Remove `-t -t` from Drydock SSH interface

Summary: These arguments prevent stderr from being routed correctly for Linux hosts and break Windows entirely.  Removing them fixes the issue.

Fix an edge case when trying to pull duplicate refs via Doorkeeper

Summary:
Report from Asana. In some unclear circumstances, we my attempt to resolve duplicate refs which currently ends up hitting a duplicate key error.

Instead, reference the same external object if we happen to be handed duplicate refs.

Test Plan:
Used this script to reproduce the issue. Applied the fix; issue went away:

  #!/usr/bin/env php
  <?php

  require_once 'scripts/__init_script__.php';

  $args = new PhutilArgumentParser($argv);
  $args->parseStandardArguments();

  $ref = id(new DoorkeeperObjectRef())
    ->setApplicationType(DoorkeeperBridgeAsana::APPTYPE_ASANA)
    ->setApplicationDomain(DoorkeeperBridgeAsana::APPDOMAIN_ASANA)
    ->setObjectType(DoorkeeperBridgeAsana::OBJTYPE_TASK)
    ->setObjectID(7253737283629); // Use a new task ID which we've never pulled.

  $refs = array(clone $ref, clone $ref);

  $asana_user = id(new PhabricatorPeopleQuery())
    ->setViewer(PhabricatorUser::getOmnipotentUser())

Add a basic push log for recording repository push events

Summary:
Ref T4195. This log serves two purposes:

  - It's a log, so you can see what happened. Particularly, in Git/Hg, there is no other way to tell:
    - Who //pushed// a change (vs committed / authored)?
    - When was a change pushed?
    - What was the old value of some tag/branch before someone destroyed it?
  - We can hand these objects off to Herald to implement pre-commit rules.

This is a very basic implementation, but gets some data written and has a basic UI for it.

Fix an error in the PolicyFilter algorithm

Summary:
`PhabricatorPolicyFilter` has a bug right now where it lets through objects incorrectly if:

  - the query requests two or more policies;
  - the object satisfies at least one of those policies; and
  - policy exceptions are not enabled.

This would be bad, but there's only one call in the codebase which satisfies all of these conditions, in the Maniphest batch editor. And it's moot anyway because edit operations get another policy check slightly later. So there is no policy/security impact from this flaw.

(The next diff relies on this behavior, which is how I caught it.)

Test Plan:
  - Added a failing unit test and made it pass.
  - Grepped the codebase for `requireCapabilities()` and verified that there is no security impact. Basically, 99% of callsites use `executeOne()`, which throws anyway and moots the filtering.
