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!)

This enables kinds that generate tasks based on those output by another kind.
For example, the test kind might generate a set of test tasks for each build
task.

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.

* Implement & document optimization (although legacy kind doesn't do much of it)
* Introduce `optimize_target_tasks` parameter to control whether tasks in the
target set can be optimized (no for try, yes for most other branches)
* Refactor to include resolved taskIds in the optimized task graph
* Include a `label-to-taskid.json` artifact.
* Introduce {'task-reference': '... <dependency-name> ...'} for referring to
parent tasks' taskId.

This adds support for the `-t`/`--talos` option, matching such jobs against
`talos_try_name`. There are no such tasks just yet.

The `taskgraph` package generates TaskCluster task graphs based on collections
of task "kinds". Initially, there is only one kind, the "legacy" kind, which
reads the YAML files from `testing/taskcluster/tasks` to generate the task
graph.
Try syntax is implemented by filtering the tasks in the taskgraph after it has
been created, then extending the result to include any prerequisite tasks.
A collection of `mach taskgraph` subcommands are provided for developers to
extend or debug the task-graph generation process.
