The task description now includes
* flexible specification of index routes (this will get simpler once buildbot
and gecko.v1 routes are removed)
* "run-on-projects", indicating the projects on which this task should run
* "{level}" is allowed in workerTypes
* For the docker-worker/docker-engine worker implementations, "docker-image"
can have the form {in-tree: in-tree-name} to use an in-tree image. This was
previously implemented in the test transforms, but it is useful for other
tasks too!
* Optimizations, currently limited to "only-if-files-changed", can be specified
for each task.
* TreeHerder groupSymbol is optional
* expires-after and and deadline-after have default values (with the former
differing for try and non-try)
* coalesce-name triggers creation of both a coalesce route and a superseder URL

If a developer adds '--rebuild N' to their try syntax they will get test jobs scheduled N times.
This is useful to determine intermittency rate.
This fixes a regression due to the recent refactoring on how we schedule tasks.
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 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.
