This introduces a 'try_task_config' method of scheduling. En lieu of (or in addition to) try
syntax, you can now check in a file called 'try_task_config.json' to the root of the source
tree. The format is either a list of task labels, or dict where task labels are the keys.
Taskcluster will simply schedule any tasks that are listed there.
This file is primarily meant to be generated by tools (which don't exist yet), as the json
format is much easier for tools to generate or consume. These tools should use an in-memory
commit to add the file so it is automatically removed again after the push.
A server-side hook will be added in bug 1380357 to prevent this file from accidentally
landing on non-try trees.

This patch enables `run-on-projects` to work appropriately for
nightly builds and tests. Initially, we were setting an empty
`run-on-projects` for nightly `build_platform`s, then explicitly
targeting the platforms in nightly-specific `target_task_method`s.
Instead, this patch enables nightlies to `run-on-projects` everywhere,
but governs the use of nightlies by either the `include_nightly`
parameter, or the `--include-nightly` try option. This lets us filter
nightly-related `target_task_method`s against `run-on-projects` without
losing all nightly tasks.
Then, enable spidermonkey tests by removing optimization from beta and
release. This patch also enables everything then disables specific
tasks, rather than disabling everything and enabling specific tasks.
Since we're beginning with a `filter_for_project` call, we should be
able to reduce these if blocks to zero over time, if desired.

Graph morphs modify the graph after optimization, without changing its meaning.
In this case, that means adding index tasks that will insert paths into the
index beyond the relatively limited number afforded in task.routes.

this patch:
- adds linux{32,64}-nightly/opt test platforms that mirror the non-nightly test platforms.
- adds an `include_nightly` per-project parameter; this is refered to in the default `target_task_method`. It's still possible to launch custom `target_task_method`s to trigger nightlies against, say, try.
- adds a `filter_for_project` method in `target_tasks.py` that allows for `include_nightly` and `run_on_projects` filtering in the various `target_task_method`s.
- adds nightly filtering into the `TryOptionSyntax` object. By default, this will be off. To trigger nightly tests on try, either submit a new decision task with a different `target_task_method` (e.g. `nightly_fennec`) or flip the `include_nightly` flag to True.
- adds the `nightly` attribute to tests if their builds have that attribute.

Instead of every file trying to get the top source directory having an
ad-hoc definition that gets wrong if the files gets moved around for
some reason, define it in a more central location.

Now that we use the real geckolib and have all dependencies vendored,
the dummy geckolib is no longer required, so we remove it.
Also, the taskgraph code for testing for Servo's presence always
passes and is no longer needed, so we remove it.
Pushed on a CLOSED TREE because ¯\_(ツ)_/¯

Stylo automation doesn't work unless Servo is present in the source
directory. This commit introduces a "check_servo" filter that prunes
tasks requiring Servo. Currently, this is implemented as a test against
platforms that are unique to Servo.
The use of relative path checking to find the topsrcdir is a bit
unfortunate. But we use this pattern elsewhere in this code.

Previously, we ran a single "target task" function to mutate the full
task graph into a subset based on input parameters (try syntax,
repository being built for, etc). This concept is useful. But
the implementation was limiting because we could only have a single
"target tasks" function.
This commit introduces the concept of "filters." They conceptually
do the same thing as "target tasks methods" but you can run more than
1 of them.
Filters are simply functions that examine an input graph+parameters
and emit nodes that should be retained. Filters, like target tasks
methods, are defined via decorated functions in a module.
TaskGraphGenerator has been converted to use filters. The list of
defined filters can be defined in the parameters dict passed into
TaskGraphGenerator. A default filter list is provided in decision.py.
The intent is to eventually convert target tasks to filters. Until
that happens, we always run the registered target tasks method via
a filter proxy function.
No new tests have been added because we don't yet have any
functionality relying explicitly on filters. Tests will be added in
a subsequent commit once we add a new filter.
While I was here, I also snuck in some logging on the size of the
graphs.

Previously, all callers outside of tests that passed
"target_tasks_method" to TaskGraphGenerator all used the same pattern
of looking for a key in the parameters and calling a function in
the target_tasks module.
Future commits will refactor how target tasks graph work. To
make the transition easier, we move the logic for obtaining the
target tasks method into TaskGraphGenerator.

In this case, the tasks must have the same schedulerId as the existing task,
so this is calculated using parameters['level'].

This uses the run_on_projects attribute introduced earlier for most branches,
adjusts the `ash` method to handle that branch as the legacy implementation
did, and updates try syntax to match builds as well as tests.
In the process, this enables optimizing target tasks, meaning that tasks
specifically requested in the try syntax might be optimized. While this is
probably not ideal, it matches the existing behavior of try (where `-j all` is
the default but all jobs are set to run only when certain files have been
modified). This change can be reverted later, in a more advanced version of
try.

This introduces a completely new way of specifying test task in-tree,
completely replacing the old spider-web of YAML files.
The high-level view is this:
- some configuration files are used to determine which test suites to run
for each test platform, and against which build platforms
- each test suite is then represented by a dictionary, and modified by a
sequence of transforms, duplicating as necessary (e.g., chunks), until
it becomes a task definition
The transforms allow sufficient generality to support just about any desired
configuration, with the advantage that common configurations are "easy" while
unusual configurations are supported but notable for their oddness (they
require a custom transform).
As of this commit, this system produces the same set of test graphs as the
existing YAML, modulo:
- extra.treeherder.groupName -- this was not consistent in the YAML
- extra.treeherder.build -- this is ignored by taskcluster-treeherder anyway
- mozharness command argument order
- boolean True values for environment variables are now the string "true"
- metadata -- this is now much more consistent, with task name being the label
Testing of this commit demonstrates that it produces the same set of test tasks for
the following projects (those which had special cases defined in the YAML):
- autoland
- ash (*)
- willow
- mozilla-inbound
- mozilla-central
- try:
-b do -p all -t all -u all
-b d -p linux64,linux64-asan -u reftest -t none
-b d -p linux64,linux64-asan -u reftest[x64] -t none[x64]
(*) this patch omits the linux64/debug tc-M-e10s(dt) test, which is enabled on
ash; ash will require a small changeset to re-enable this test.
IGNORE BAD COMMIT MESSAGES (because the hook flags try syntax!)

Jobs reporting to treeherder should rely on the task route for project,
revision, and pushlog ID rather than things stuffed into task.extra.treeherder.
This also removes the need for a revision_hash that was calculated by mozilla-taskcluster.
