Add setup script
I added a setup script which runs during the build process of the docker image and also modified the folder structure a little for a better fit to the others. Please feel free to merge it if you are happy with the changes.
The old module-image for the shared runners will be discontinued on October 31. All users still referencing gitlab-registry.mpcdf.mpg.de/mpcdf/module-image in their CI pipelines need to switch to the new CI images now, see instructions here.
