This causes actions to fail on graphs with large parameters, such as
release graphs and try pushes.

Previously, this code looked parameters under `gecko.v2`, but that doesn't work
for projects using the out-of-tree taskgraph code, or Thunderbird. This moves
the parameter loading slightly later to vary the index used based on trust domain.

This allows the target tasks to include cached tasks, which by default, get
optimized out of the graph on on-`try` branches.

Eventually, workers will provide these variables directly
(https://bugzilla.mozilla.org/show_bug.cgi?id=1460015). But for now, this
ensures that TASKCLUSTER_ROOT_URL is set everywhere, and TASKCLUSTER_PROXY_URL
is set wherever the proxy is active.
The setup for the mach commands defaults to https://taskcluster.net for user
convenience. When the production instance's URL changes, we can simply change
that default.
This changes the docker build process propagate TASKCLUSTER_ROOT_URL into the
docker images where necessary (using %ARG), specifically to create URLs for
debian repo paths.

`mach artifact toolchain` gets task definitions from taskgraph, to get the
index path to find the artifacts at. Now that these index paths depend on the
digests of fetch tasks, those kinds need to be loaded as well. This adds a
supported API to get task definitions for a given kind, which loads all the
kind dependencies.

For kind=hook, the spec doesn't include this value as it's untrustworthy.
For kind=task, it's still untrustworthy, but there is no privilege escalation
so that's not important. Still, it dramatically expands the size of the task
definition.

The latest python-zstandard uses a newer zstandard that is faster.
It also has wheels available, which means installation doesn't require
Python development headers, etc.

Now that `mach taskcluster-build-image` can, we can avoid all the manual
handling based on curl and jq in the image builder.
An additional advantage on relying on `mach taskcluster-build-image`
doing more is that less changes to the build-image.sh script will be
necessary, and thus less updates of the image builder docker image.

The zstd command we spawn, if available at all, might be the wrong
version: zstd changed its stream format in an incompatible way at some
point, and the version shipped in e.g. Ubuntu 16.04 uses the old format,
while the version taskcluster relies on uses the new format.
Relying on gps's zstandard library allows to ensure we use the right
version. Another advantage is that we can trivially pip install it in a
virtualenv if it isn't available on the system running the command.
If we're ridding ourselves of the subprocess spawning for zstd, we might
as well cover curl as well. Especially considering the error handling
when subprocesses are involved is not trivial, such that the current
error handling code is actually broken and leads to dead-lock
conditions, when, for example, curl is still waiting for the python side
to read data, but the python side is not reading data anymore because
an exception was thrown in the tar reading loop.

Ideally, we'd simply use the --build-arg docker argument along with ARG
in the Dockerfile, but that's only supported from Docker API 1.21, and
we're stuck on 1.18 for the moment.
So we add another hack to how we handle the Dockerfile, by adding a
commented syntax that allows to declare arguments to the Dockerfile.
The arguments can be defined in the docker images kind.yml file through
the `args` keyword. Under the hood, they are passed down to the docker
image task through the environment. The mach taskcluster-build-image
command then uses the corresponding values from the environment to
generate a "preprocessed" Dockerfile for its context.

Initially this will skip toolchain task optimizations, which avoids hashing
local directory contents and speeds up taskgraph generation by about 25%.

Add a release promotion custom action for releng's TC release promotion migration work.
This action generates a graph dependent on previously built tasks. To track these, we add the `do_not_optimize` and `existing_tasks` parameters. The `do_not_optimize` parameter specifies tasks that we want to explicitly exclude from taskgraph optimization. The `existing_tasks` parameter specifies a label-to-taskid map for tasks from previous graphs.
