Stopping ROS remotely

[samdai01]

Purpose

As a precursor to the SOFT manual control feature implemented for ELEC, we need to figure out how to stop a running instance of ROS without the ability to CTRL+C through a terminal.

Ideally, this would be possible through the use of ps -aux and kill -9.

Please experiment and report how we can stop ROS.

If the above doesn't work, a cleaner but more complex solution is to use https://robotics.stackexchange.com/questions/81154/proper-way-to-shutdown-rosout-roscore

I have confirmed we can kill ROS with kill commands
