Attempt #4 to convert telemetry to the typ framework.

Attempt #4 to convert telemetry to the typ framework.

This switches telemetry to use the typ python testing framework,
which should allow us to run tests in parallel.

The prior attempt was foiled by tools/chrome_proxy not having been
updated; this attempt includes that change.

Dave, please take another look and see if things look okay?

I would've uploaded the prior attempt so you could see a diff, but the renaming
of unittest -> unittest_util would've made it unintelligible.

The main change is in tools/chrome_proxy/run_tests, which has been updated to
wrap things the same way tools/telemetry/run_tests and tools/perf/run_tests do.
