Summary:
Ref T13677. Drydock has a hard-coded and fairly arbitrary limit which prevents a resource pool from growing more than 25% at once.
This is vaguely reasonable for resources which allocate quickly, but suffocating for slower resources. It's also wholly arbitrary, and the "one per lease" limit introduced in D21807 should do a better job of covering the same ground while generally being more reasonable, expected, and predictable.
Test Plan: Ran Drydock allocations without the throttle, saw faster pool growth.

Summary:
Ref T13677. Currently, one lease may cause multiple resources to allocate simultaneously if it starts allocating one, then wakes up from a yield later on and still sees no available resources.
This is never desired -- or, at least, produces desirable behavior only entirely by accident. Normally, it causes an excess of resources to allocate.
This is not a catastrophic problem: the extra resources usually get used sooner or later or cleaned up; and the total amount of badness is limited by overall resource allocation limits.
However, this behavior is also suppressed by an artificial "25% of current pool size" growth limit throttle which I intend to remove. Removing this throttle without fixing the allocator behavior could make this "too many resources" problem worse.
Change the allocator so that a lease that has started allocating a resource won't allocate another resource until the first resource leaves the "pending" state.
This also fixes some general oddness with the allocator and attempts to simplify the structure.
Test Plan:
- Ran 8 taskmasters.
- Destroyed all resources and leases.
- Leased 4 working copies.
- Saw exactly 4 resources build and lease, all simultaneously.
- Destroyed all resources and leases.
- Leased 32 working copies.
- Saw exactly 32 resources build and lease, approximately 8 at a time (limited by taskmasters).
- Destroyed all leases (but not resources).
- Leased 32 working copies, saw them satisfied by existing resources.

Summary:
See T13673. Recent versions of Git (and older versions with backported security patches) now refuse to run Git commands if the top-level repository directory is not owned by the user running the command.
Currently, we "sudo" to that user only when performing writes, so upgrading Git can aggressively break a Phabricator system by knocking out essentially all Diffusion/Conduit read pathways.
As an immediate mitigation, just "sudo" in all cases where a daemon user is available. This fixes the problem, and seems like the least-bad approach. The downside is that the web user may theoretically have fewer privileges than the daemon user and this could reduce the number of layers an attacker armed with some other Git vulnerability might have to get through to do something dangerous (e.g., perform a write on a pathway where only reads are expected), but any separation between the web and daemon accounts is essentially theoretical and has never been enforced.
Test Plan: Applied patch to impacted Phacility shard, saw Diffusion work properly again.
