Initial version of combining rtsp_ai_player and camera modules.

Functionality has been written to rtsp_ai_player.

TODO!!
- move functionality of camera module misc/rtsp_ai_player/aienginegimbalserver.cpp
- implement all signals in AiEngineGimbalClient
- get drone position from autopilot and send it to AiEngineGimbalServer
