Document gazebo client connection with gazebo server about mav

[elpiel]

I dunno about gazebo client, but http://qgroundcontrol.com/ works and it s awesome :D

That's true, however, the gzclient is not an operational software but the GUI for the simulation tool.
It gives you the possibility to add objects, change parameters and so on.

Now we have information about connecting with gzclient inside docker, however, we have some issues regarding the loading of the models and ign-transport.

I'm adding them to this issue as tasks.

Due to the fact that PX4-Autopilot uses Ubuntu 18.04, this means that it uses gazebo 9.0.0 and while newer versions of Ubuntu (like 20.04) have v9 of gazebo (gazebo9 packages) it's newer than 9.0.0 and does not connect to the server.

I found this repo that has ROS/Gazebo Dockerfiles and uses X server and remote connection to the running container with a mount of the display (I believe) but I was not able to replicate the display part in a new Docker image. Maybe we can try using that image and see if it would work? 🤔
