To date we have variously specified both worker-type and worker-implementation,
often manually coordinated. We also embedded a few awkward assumptions such as
that the native engine only runs on OS X.
But a worker type has one and only one implementation, and that implementation
is stable over time (as changing it would require simultaneous landings on all
trees).
Instead, this change makes worker-type the primary configuration, and derives
both a worker implementation (defining the payload format) and worker OS
(determining what to include in the payload) from that value. The derivation
occurs when deciding how to implement a particular job, where the run_using
functions are distinguished by worker implementation.
The two-part logic to determine how and where to run a test task based on its
platform is combined into a single transform, `set_worker_type`.
This contains some other related changes:
- MOZ_AUTOMATION is set in specific jobs, rather than everywhere docker-worker
is used
- the URL to test packages is factored out into a shared function
- docker-worker test defaults are applied in `mozharness_test.py`
- the WORKER_TYPE array in `task.py`, formerly mixing two types of keys, is
split
- the 'invalid' workerType is assigned an 'invalid' implementation
- all tasks that do not use job descriptions but use docker-worker, etc. have
`worker.os` added
Tested to not produce a substantially different taskgraph for a regular push, a
try push, or a nightly cron.

We add the following command line options to Taskcluster try syntax:
--spsProfile - enable profile mode.
--rebuild-talos <N> - retrigger talos tests N times.
--setenv <VAR>=<val> - add extra environments variables.
--tag <TAG> - run tests only the tag TAG.
--no-retry - doesn't retry failed jobs.
We have a chicken-egg problem, as we first generate the full task graph
and then parse the try message. But the graph generation step needs to
know the try message to process the aforementioned options. The
solution is to parse the message before graph generation and then
pass the command line options to the transforms. Then, each transform
can look at the option that interests it and process it accordingly.
The message parse function is configured in kind.yml, which gives some
flexibility for future implementations of alternative syntaxes.
