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.

Note that the to_json method prefers the taskgraph's dependencies information
(edges) to that from the task.dependencies entries. At a few points in
task-graph generation, these values differ, although that is expected (for
example, the full task set contains no edges, but that information is still in
task.dependencies). Unifying that representation leads to some difficulty with
task transforms that reach into the dependency tree (beetmover), so the
different representations are left as-is.

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.

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!)

For example, the test kind might generate a set of test tasks for each build
task.

* 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.

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.
