Crane JupyterHub config change and restart

Scheduled for Friday 5th April 2019 at 16:00 (Central Time (US & Canada))

Schedule/description of work

We are reconfiguring JupyterHub to remove the "Local Jupyter Notebook" option. This service has become more popular, and the single Crane login node cannot keep up with the load. This has lead to performance issues for both Jupyter and login node users.

The "Notebook via SLURM Job" options will give each user dedicated CPU and memory resources, as it runs inside a cluster job. Several worker nodes are dedicated to JupyterHub use, so there should be little to no wait.
