[autotest] Delete support for parameterized jobs.

This deletes the `create_parameterized_job()` RPC endpoint and the
associated (unused!) "parameterized_jobs" config setting.  It also
garbage collects code made unreferenced by these deletions.

BUG=chromium:679903
TEST=unit tests, and run push_to_prod suite in a local instance
