Arducopter \ SITL - basic action functions

[ygratz]

Hi, I'm using MAVSDK 1.4.6. With Arducopter \ SITL.

I try to implement very basic things, but some of them do not work for some reason:

1. action.takeoff() - I note that I must set to guided mode in the SITL, else the takeoff() is denied.
2. action.set_takeoff_altitude() it works. However its return value is wrong.
3. action.goto_location() is denied.

Is there a workaround to these issues? If so please advise. Thank you
