[rianders]

The autonomous, data collect, and thr_step should be virtual buttons that can be overridden with a launch flag. This would allow at launch time the ability to specify the autonomous mode and relevant data.

Each mode could launch with the correct start values. This could be sent to docker and do a restart with appropriate settings passed to the car for driving.

The argparse for mode was added, but there's plenty more todo.
