Klaas van Schelven 200ea5eb84 Docker image: Ubuntu -> python-slim
* I'd rather harmonize with "the docker way" than with my own recommended setup
* slim: expectation is that this is smaller (not checked)
* this is a 2-stage build (slim has no gcc, needed for mysql)
* PEP668 does not apply here ("externally managed"), which leads to
* better ergonomics: no env/bin/some-command
