Summary:
Fixes T9994. Currently, when Drydock can't allocate a new resource because some limit has been reached, it waits patiently for a resource to become available.
It is possible that no resource will ever become available. Particularly with "Working Copy" resources, the new lease may want a copy of `rB`, but the resource may already be maxed out on `rA`.
Right now, no process exists to automatically reclaim the unused `rA`.
When we encounter this situation, try to reclaim one of the other resources if it is just sitting there unused.
Specifically:
- Add a "reclaim" command which means "release this resource //if// it is completely unused".
- Add a `bin/drydock reclaim` to send this command to every active resource.
- When we try to acquire a resource and can't, but only because of some kind of limit / utilization problem, try to release an unused resource to free up some room.
Test Plan:
- Set "Working Copy" resource limit to 1.
- Ran "Test Configuration" in `rA`, which worked.
- Ran "Test Configuration" in `rB`, which hung forever.
- Applied patch.
- Ran "Test Configuration" in `rB`, saw it reclaim the `rA` resource, use the slot, then succeed.
- Ran "Test Configuration" in `rA` again, saw it grab the slot back.
- Ran `bin/drydock reclaim` and saw it reclaim a bunch of old orphaned resources.

Summary:
Ref T9994. This fixes the first issue discussed on that task, which is that when a merge fails after "arc land", we would not clean up all the leases properly.
Specifically, when a merge fails, we use `queueTask()` to schedule a followup task. This followup destroys the lease and frees the underlying resource.
However, the default behavior of `queueTask()` is to //not queue tasks// if the parent task fails. This is a reasonable, safe behavior that was originally introduced in D8774, where it kept us from sending too much mail if a task did "send some mail" and then failed a little later on and got retried.
Since I think the default behavior is correct, I just special cased the behavior for Drydock to make it queue even on failure. These are the only types of followup tasks we currently want to queue on main task failure.
(It's possible that future Blueprints might want some kind of more specialized behavior, where some tasks queue only on success, but we can cross that bridge when we come to it.)
Test Plan:
- See T9994#149878 for test case setup.
- I ran that test case again with this patch, and saw the followup task queue properly in the `--trace` log, a correspoinding update task show up in `/daemon/`, and the lease get destroyed when I ran it a moment later.

Summary:
Ref T9252. Right now, we have very strict limits on Drydock: one lease per host, and one working copy per working copy blueprint.
These are silly and getting in the way of using "Land Revision" more widely, since we need at least one working copy for each landable repository.
For now, just remove the host limit and put a simple limit on working copies. This might need to be fancier some day (e.g., limit working copies per-host) but it is generally reasonable for the use cases of today.
Also add a `--background` flag to make testing a little easier.
(Limits are also less important nowadays than they were in the past, because pools expand slowly now and we seem to have stamped out all the "runaway train" bugs where allocators go crazy and allocate a million things.)
Test Plan:
- With a limit of 5, ran 10 concurrent builds and saw them finish after allocating 5 total resources.
- Removed limit, raised taskmaster concurrency to 128, ran thousands of builds in blocks of 128 or 256.
- Saw Drydock gradually expand the pool, allocating a few more working copies at first and a lot of working copies later.
- Got ~256 builds in ~140 seconds, which isn't a breakneck pace or anything but isn't too bad.

Summary:
Ref T9252. This fixes a bug from D14236. D14272 discusses the observable effects of the bug, primarily that the window for racing is widened from ~a few milliseconds to several minutes under our configuration.
This SQL query is missing a `GROUP BY` clause, so all of the resources get counted as having the same status (specifically, the alphabetically earliest status any resource had, I think). For test cases this often gets the right result since the number of resources may be small and they may all have the same status, but in production this isn't true. In particular, the allocator would sometimes see "35 destroyed resources" (or whatever), when the real counts were "32 destroyed resources + 3 pending resources".
Since this allocator behavior is soft/advisory this didn't cause any actual problems, per se (we do expect races here occasionally), it just made the race very very easy to hit. For example, Drydock in production currently has three pending working copy resources. Although we do expect this to be //possible//, getting 4 resources when the configured limit is 1 should be hard (not lightning strike / cosmic radiaion hard, but "happens once a year" hard).
Also exclude destroyed resources since we never care about them.
Test Plan:
Followed the plan from D14272 and restarted two Harbormaster workers at the same time.
After this patch was applied, they no longer created two different resources (we expect it to be possible for this to happen, just very hard).
We should still be able to force this race by putting something like `sleep(10)` right before the query, then `sleep(10)` right after it. That would prevent the allocators from seeing one another (so they would both think there were no other resources) and push us down the pathway where we exceed the soft limit.

Summary:
Ref T9252. This is mostly a fix for an edge case from D14236. Here's the setup:
- There are no resources.
- A request for a new resource arrives.
- We build a new resource.
Now, if we were leasing an existing resource, we'd call `canAcquireLeaseOnResource()` before acquiring a lease on the new resource.
However, for new resources we don't do that: we just acquire a lease immediately. This is wrong, because we now allow and expect some resources to be unleasable when created.
In a more complex workflow, this can also produce the wrong result and leave the lease acquired sub-optimally (and, today, deadlocked).
Make the "can we acquire?" pathway consistent for new and existing resources, so we always do the same set of checks.
Test Plan:
- Started daemons.
- Deleted all working copy resources.
- Ran two working-copy-using build plans at the same time.
- Before this change, one would often [1] acquire a lease on a pending resource which never allocated, then deadlock.
- After this change, the same thing happens except that the lease remains pending and the work completes.
[1] Although the race this implies is allowed (resource pool limits are soft/advisory, and it is expected that we may occasionally run over them), it's MUCH easier to hit right now than I would expect it to be, so I think there's probably at least one more small bug here somewhere. I'll see if I can root it out after this change.
