Add exercise for the Docker image creation lesson
This adds an exercise for creating a Docker image with relation to data science in Python.
- Reuses most of the concepts learned in the lesson.
- Introduce two new instructions available in Dockerfile by providing a hint and documentation.
- Reuse port exposition from lesson 2, starting containers.
- The
EXPOSEinstructions is optional, only serves for documentation purpose. It's not so important if learners don't add it to the Dockerfile. Can be explained afterwards.
