JupyterHub with CAS Authentication

Build a docker image that includes the JupyterHub CAS Authenticator.

To run JupyterHub with CAS authentication using kubespawner, use helm to install JupyterHub.

Instead of using the simple configuration example in the guide, use a configuration file that specifies a custom image and configures the authenticator.

    config:

      cas_service_validate_url: https://cas.example.edu/cas/p3/serviceValidate # Requires CAS 5
      # cas_service_validate_url: https://cas.example.edu/cas/serviceValidate # Works on CAS 3

The sample configuration file also exists in the git repository in config.yaml.
