try generic openid-connect config

[rabernat]

After #604 failed, I'm trying a new approach.

Here is secrets/staging.yaml.

pangeo:
  jupyterhub:
    auth:
      custom:
        config:
          client_id: "XXX"
          client_secret: "XXX"

[rabernat]

This is based on https://zero-to-jupyterhub.readthedocs.io/en/latest/administrator/authentication.html#openid-connect

[rabernat]

This deployed successfully, but is not quite working. The auth link is https://staging.hub.pangeo.io/hub/oauth_login?next=

Something must not be set right.

In the hub log, I'm seeing

[E 2020-05-12 16:53:37.031 JupyterHub generic:144] OAuth user contains no key nickname: {}
[W 2020-05-12 16:53:37.031 JupyterHub base:714] Failed login for unknown user
[W 2020-05-12 16:53:37.033 JupyterHub log:174] 403 GET /hub/oauth_callback?code=[secret]&state=[secret] (@10.128.0.143) 423.83ms

It seems that the oauth user is cached. I'm going to try deleting cookies.

So after clearing cookies, I was able to log in via auth0. Yay! But then I hit the same error

[E 2020-05-12 17:06:03.515 JupyterHub generic:144] OAuth user contains no key nickname: {}
[W 2020-05-12 17:06:03.516 JupyterHub base:714] Failed login for unknown user

So it seems that we are not getting the proper user data.
