roschaefer 7f2cd575cb Push all docker images at VERSION to dockerhub
Inspired by the tagging of e.g. `node` on dockerhub:
https://hub.docker.com/_/node/?tab=description

I would like to push the current version of all our images to dockerhub.
This is a first step to push to production later on.

If sb. increments the VERSION file, this is considered a release.
