This changes the build process even further. Instead
f using `wget` to fetch the current code, `git` is used.
This allows for faster switching between branches,
because only the differences between them have to be
fetched from the server.

But the main advantage is that the build cache can
finally be used as designed by Docker. Repetitive
builds are very fast now. This is also true between
branches and tags, as long as the `requirements.txt`
file doesn't change.

Hint: If you're building a specific version by tag name, the `--no-cache` argument is not strictly necessary.
This can increase the build speed if you're just adjusting the config, for example.
