Set a config key on the UAV. A list of keys can be found in the section "Constants" -> "Configuration" in the docs for UAV::Pilot::ARDrone::Driver. To set a --key option, take off the ARDRONE_CONFIG_ at the start of the config key name. For instance, to set ARDRONE_CONFIG_VIDEO_CODEC_FPS, you would instead set video_codec_fps (lowercase is OK).
