Robert Schroll 8a5fc8044a examples/service-whoami-flask: Add scope to user role 
For ordinary users to access the service, they need an appropriate
scope added to the user role.  This adds that role in the
jupyterhub_config.py, as well as a note about this in the README.
It also updates the ouptut that comes form the whoami service.

Authenticating a flask service with JupyterHub

Uses jupyterhub.services.HubOAuth to authenticate requests with the Hub in a flask application.

Run

  1. Launch JupyterHub and the whoami service with

    jupyterhub --ip=127.0.0.1

  2. Visit http://127.0.0.1:8000/services/whoami/

After logging in with your local-system credentials, you should see a JSON dump of your user info:

{
  "admin": false,
  "groups": [],
  "kind": "user",
  "name": "queequeg",
  "scopes": [
    "access:services!service=whoami",
    "read:users:groups!user=queequeg",
    "read:users:name!user=queequeg"
  ],
  "session_id": "a32e59cdd7b445759c58c48e47394a38"
}

This relies on the Hub starting the whoami service, via config (see jupyterhub_config.py). For ordinary users to access this service, they need to be given the appropriate scope (again, see jupyterhub_config.py).

A similar service could be run externally, by setting the JupyterHub service environment variables:

JUPYTERHUB_API_TOKEN
JUPYTERHUB_SERVICE_PREFIX
