   Args:
     results_tracker: An instance of a log parser class, which has been used to
         process the test output, so it contains the test results.
     system: A string such as 'linux-release', which comes from perf_id.
     test: Test "suite" name string.
     url: Dashboard URL.
     build_dir: Build dir name (used for cache file by results_dashboard).
     mastername: Buildbot master name, e.g. 'chromium.perf'.
         WARNING! This is incorrectly called "masterid" in some parts of the
         dashboard code.
     buildername: Builder name, e.g. 'Linux QA Perf (1)'
     buildnumber: Build number (as a string).
     supplemental_columns_file: Filename for JSON supplemental columns file.
     extra_columns: A dict of extra values to add to the supplemental columns
         dict.
