This decreases the scheduling algorithm from a CT_MEDIUM (0.8) threshold to
CT_LOW (0.7). It also reduces the threshold used in the manifest resolving
algorithm down to 0.5. This means we'll have more "ride-along" manifests that
happen to be in the same chunk as the more important ones.

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.
To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.
5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

Depends on D90159

This removes the last uses of the 'push-interval-10' and 'push-interval-20' strategies.
They are being removed because they are dangerous in that its easy to accidentally not run
tasks when they should.
Instead, task authors should decide whether they want their tasks to run on
"backstop" pushes (run everything) or "expanded" pushes (run more than usual,
but still not as much as a backstop). Note that using "expanded" means the task
will *also* run on backstop pushes. It'll just additionally run on "expanded"
pushes.
In practice 'backstop' pushes will be every 20th push and 'expanded' pushes
will be every 10th push. Though this may vary due to the time component in
backstops.
Differential Revision: https://phabricator.services.mozilla.com/D89503
This is a nomenclature change + refactoring. Now there is only a single
"backstop" push. Which is currently set to every 20th push on autoland (or
every push on non-autoland branches).
Now there is also a concept of an "expanded" push. These are pushes that run
more stuff than usual, but not as much as a backstop normally would. These are
currently set to run at half the interval of a backstop.
Concretely, here are the strategy changes:
* Renamed 'backstop' -> 'skip-unless-backstop'
* Introduced the 'skip-unless-expanded' strategy which has 'skip-unless-backstop' baked in
* Merged 'optimized-backstop' into the 'test' strategy (with expanded comments)
* Baked both 'skip-unless-expanded' and 'skip-unless-backstop' into the 'test' strategy
Differential Revision: https://phabricator.services.mozilla.com/D89501
It turns out that 'Not' is needed to negate "backstops". E.g, we normally
we want to use a pattern like so:
All("skip-unless-backstop", "test")
Since 'skip-unless-backstop' returns False on backstop pushes, it disables
the test strategy there.
However, suppose we wanted to run a special optimization, *only* on backstop
pushes. I.e, the opposite of the above example. Then we need to use:
All(Not("skip-unless-backstop"), "test-backstop")
Depends on D89500
Differential Revision: https://phabricator.services.mozilla.com/D89734
This patch cleans up some of the backstop strategy names. Specifically:
1. Rename 'full-backstop' -> 'backstop'. The old 'backstop' algorithm was
unused anyway, so there is no conflict. It is also just defined directly in
the decorator rather than using 'Alias'.
So now rather than 'full-backstop' and 'optimized-backstop', it's just
'backstop' and 'optimized-backstop'.
2. Remove 'backstop-X-hours-Y-minutes' strategies, and replace them with
the corresponding 'push-interval-X' strategy.
This means we lose the time component in the 'optimized-backstop'. But it isn't
a problem, because we shouldn't be using a time component there at all anyway
(we should just use it with the 'backstop').

Certain tasks are meant to perform follow-up work to another task. For example,
a 'signing' task signs an artifact from a dependency task. An 'upload-symbols'
tasks uploads an artifact from a dependency task.
In general, we only want to run these types of tasks when the dependency task
is running. But in practice, these tasks often cause the dependency to get
pulled in.
We've tried to fix this in the past by making the 'run-on-projects' and
'optimization' keys match their primary dependency. But it's very easy to
mess this up, and some optimizations (like bugbug) take the content of the
task definition into account. So even if both tasks use the same optimization,
they could have different results.
This revision adds a new 'if-dependencies' key that denotes a task that should
only run if one of the dependencies specified in this list is also run. It
will allow us to stop playing whack-a-mole when trying to make sure tasks
aren't being pulled in solely due to these types of dependencies.
This feature is implemented independently of the 'optimization', so tasks that
specify this can still be optimized even if their primary dependency does run.
Differential Revision: https://phabricator.services.mozilla.com/D80508
This is needed as future revisions will refactor the optimization process to be
two pass. So we can't be sure if a task is optimized or not until the very end.
