Switches ocs-util to jupyterlab

[jlashner]

Switches ocs-util to using jupyter lab instead of jupyter notebook.

Description

Migrates jupyter notebook configurations to jupyter lab.

Motivation and Context

Jupyter lab is a pretty big upgrade to jupyter notebook, and has been requested by Kenji, and is currently being used in the smurf-jupyter environment. Allows you to view other filetypes like images and csvs, run terminal sessions, and more.

Thanks for the switchover. I think we can drop jupyter from the requirements file, but correct me if I'm wrong.

Do we still need jupyter? It doesn't look like a dependency to jupyterlab.
