Add nteract jupyter extension to requirements.txt based setups

Didn't add to conda, since there is currently no way to add
pip packages to our conda frozen setup (due to
https://github.com/conda/conda/pull/6438).

This means nteract will be available only when used with
requirement.txt, and not when used with environment.yml files.
