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

Rename to taskgraph.transforms.task.
This also adds some Required and Optional declarations to the schema to be explicit,
and adjusts the transform to handle treeherder being optional.

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.
Currently, TaskCluster tasks tend to use the "workspace" directory as
a cache that manages the source checkout *and* additional state.
Historically at Mozilla, we've lumped "source checkout" and "workspace"
(sometimes known as an "objdir") into the same directory. This is
not ideal. Ideally, there is an immutable, read-only source checkout
and all files produced from that source live in a separate directory.
In this commit, the "workspace" directory for the "lint" image has been
renamed to "checkouts" and all tasks using the image have been updated
accordingly. By having "checkout" in the name, we clearly identify this
cache as being relevant to source checkouts, which IMO can serve a
different role from "workspaces." This distinction is important, as the
next commit will prevent the "checkouts" cache from getting optimized
out in certain tasks.
To hammer this point home, documentation on common caches has been
introduced.

A limitation of traditional docker build context generation is it
only includes files from the same directory as the Dockerfile. When
repositories have multiple, related Dockerfiles, this limitation
results file duplication or putting all Dockerfiles in the same
directory (which isn't feasible for mozilla-central since they would
need to be in the root directory).
This commit enhances Dockerfiles to allow *any* file from the
repository checkout to be ADDed to the docker build context.
Using the syntax "# %include <path>" you are able to include paths
or directories (relative from the top source directory root) in the
generated context archive. Files add this way are available under the
"topsrcdir/" path and can be ADDed to Docker images.
Since context archive generation is deterministic and the hash of
the resulting archive is used to determine when images need to be
rebuilt, any extra included file that changes will change the hash
of the context archive and force image regeneration.
Basic tests for the new feature have been added.

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.
