Dustin J. Mitchell f8a58269bd Bug 1359976: base worker payload generation on worker-type; r=wcosta r=aki
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.
