Reland "Verify the arguments for WebRTCPerfTest"

The first attempt failed because we dropped perf_id, as the perf
dashboard has deprecated it. However, our local test runner still
requires perf_id before it uploads the metrics*.

Coupling with crrev.com/c/2830211, this CL reads the perf_id from
source side configuration and passes it to test runner.

*: Another CL will update perf_id in test runner to
   perf_builder_name_alias to reduce the confusion.

Original change's description:
> Verify the arguments for WebRTCPerfTest
>
> This is an intermediate CL prior to a full migration of WebRTCPerfTest.
> Before we completely remove the recipe side conf for test_spec, we
> need to verify the specs from source side are consistent.

Recipes

If you're here to make a change to ‘recipes’ (the code located in the recipes directory), please take a look at the README for more information pertaining to recipes.

Style

The preferred style is PEP8 with two-space indent; that is, the Chromium Python style. Functions use lowercase_with_underscores, with the exception of the special functions RunSteps and RunTests in recipes. Use yapf (git cl format --no-clang-format) to autoformat new code.
