Drone: Create ROS Integration Plan Doc

[Roozki]

We need to plan out how we want to integrate the drone into the rest of the system.

This plan could be to not integrate the drone with ROS, and have the done on an independent system.

General Action items:

1. Brainstorm different potential uses of the drone's data for the rest of the system, assuming seamless ROS integration
2. Figure out how difficult integration would be, and weigh against the benefits. Decide what level of ROS integration we will aim for this year.
3. Roughly document this process and what we chose to do.
