Move docker config into docker-compose yaml files
What does this MR do?
Most of the changes to the docker images went into the foodsharing-dev/images repo now, it's better that way as docker-compose will not need to rebuild local images on change (just inc the version).
How confident are you it won't break things if deployed?
Just test/dev change.
