This is not currently supported - see Issue #169.

Commands are sent from DroneKit-Python using Vehicle.send_mavlink() (and the message_factory). There are a few examples of sending messages in the guide. For this to work the command has to be supported in the vehicle’s GCS_MAVLink.cpp file (otherwise the message will be recieved but the vehicle won't know what to do with it).

The problem is that you can send the message and the autopilot will respond. However in DroneKit there is no support yet for getting a specific response to the sent message back and handling it.

Your only option at the moment is to hook all messages and see if you can extract the one that is of interest to you. I have not tried this!
