[Telemetry] Update arguments printed by ./run_benchmark --list.

[Telemetry] Update arguments printed by ./run_benchmark --list.

This CL coordinates with the recipe switchover to chart JSON by changing the
Telemetry commands that run_benchmark emits to pass --output-format=chartjson
and --upload-results instead of --ouput-format=buildbot.

This change is part of what will need to be done to switch the recipes to use
chart JSON. There is still a problem that, currently Annie's code wants to
generate a temporary file and pass that as --output=<temp_file_name> to
Telemetry.

Tony, do you know if it will be possible to add additional arguments to commands
that are returned by Telemetry before actually passing them to be run, to
account for this?

Recipes bakes in the idea of one step returning json to be used later (which is
awesome). Check out the pattern that is used for listing perf tests:

Notice how we pass an output file and use it later. We can do the same thing w/
--output and --output-format.

We can pass whatever args we want when we run the tests here:
