Size of the docker container

[sjunges]

In our dockerfile, we currently use multiple layers with multiple compile commands. This generally leads to big docker containers. An open question is whether we can make these docker containers smaller.

There is definitely some room for improvement by combing commands in one layer.
Another possible option could be to simply install Storm via CMake and then remove all the build artifacts.

I like this second option as being particularly clean...

I agree that installing within the Docker container is the best option.

This issue then depends on #527.
