Update docker image with driver permissions

[agalbachicar]

Update the base Dockerfile adding permissions to the file /dev/dri/card0 to the user gazebo.

@Shokman , I made some tests on how to change permissions to the file /dev/dri/card0 so as gazebo user can load Gazebo without problems, but this file does not exists in Docker compilation time so any command trying to modify it will fail.

I suggest creating a script, which is run at the beginning, and copy to the image at compilation time. Then, the first thing to do will be changing the permissions to that file and then running tmux. Do you agree?

@agalbachicar do you have an update the status of this one?

[agalbachicar]

@basicNew I have done some preliminary tests on this. We cannot add a command to the Dockerfile to change the permissions to this file, because at docker build time it does not exist. Some possible solutions to this are:

• Add en ENV variable to the images that uses Intel drivers and add a startup script that does this at startup.
• Pass the ENV variable with the run_simulator script. We need to make use of the startup script here too to change the permissions.

The use of a startup script will have two uses now, one will be change the permissions of that file and the other is to source the variables in setup.bash file.

Thanks for the update @agalbachicar . Let's tackle this on next sprint so we can forget about this issue.

Btw @agalbachicar , shouldn't we move this issue to the BB repo now that we are doing the reorganization?

[agalbachicar]

@basicNew you're right. I'll move it to the new repository and I'll try to make a revision of the docker related issues too so we don't lose the history.

Great, thanks!
