[drivers] MAVLink server for 3DR Solo Drone should be ported to python 2.7, instead of 3.5

[jmplaza]

In order to be fully compatible with ROS Kinetic in JdeRobot we keep the code at Python 2.7.

@Diegojnb is this video with the 2.7 release of this driver or with the 3.5 one?.Great job, by the way :-)

In addition it should be changed to accept YML configuration files instead of old-fashioned, ICE style, .cfg

[Diegojnb]

I have been looking for the dependencies that apply to this driver and are only necessary to have installed pyserial and pymavlink, both can be installed using: pip install (pyserial or pymavlink).

Currently my installed versions are pyserial = 3.0.1 and pymavlink = 2.2.8.

It would be necessary to make a debian package but I do not know how they are currently done and I would like you to help me out.

Thanks.
