this installs code-server and exposes it as port 9999 on the limo when the container is started.

So, one can directly go to the limo IP at port 9999 and use VSCode in the browser, including terminal etc. And one can therefore also simply execute local code on the robots themselves.

Maybe worth trying on an actual limo, @cooperj ?

I have tested it locally, and I think it's working. There is also a new configs/docker-compose-dev.yaml which can be used to overwrite for development and testing of the config locally, but that's only for anyone developing/testing this repository, and not be used generally.

But with that test, I managed to open http://localhost:9999 and had a nice development environment directly in the container, with all things to install packages etc.

Note: I expose this on port 9999 without any authentication. So, anyone can access the robot container (but only the container!) and mess with it. Which should be fine, as we can simply delete the container and make a new one of it's been messed up.

Does not work - when I go to port 9999 I get back an empty response? Is this correct?

No surprise, as we haven't released this PR in the image... if you just run it on the robot for now it will only pull the released (version-ed) image, as it should.

Approved, changes applied as discussed.

@cooperj I presume you tested on a limo?
