Noetic development branch

Per the instructions on https://sdk.rethinkrobotics.com/intera/Gazebo_Tutorial there should be a branch called `noetic_devel` in this repo. However, it does not look like it has been created yet.

Is support for ROS Noetic planned?

We are looking for a way to use Python 3 and simulate Sawyer in Gazebo - if there is some other way to do this, it would be nice to know.
