Original issue's description:
> Move Html and BuildbotPageMeasurementResults to {Html,Buildbot}OutputFormatter.
> 
> This preserved the current output of each
> --output-format=buildbot|html. We may want to simplify the output for
> --output-format=html.
> 
> Refactored results_options.py slightly to better accommodate
> OutputFormatter (now --output-format=none is also using
> OutputFormatter code path).
