[earthscope] Restrict dask-gateway access

[GeorgianaElena]

Context

dask/dask-gateway#863 allows dask-gateway access based on group membership.

Docs at https://gateway.dask.org/authentication.html#using-jupyterhub-s-authentication

What we need to do

1. Setup jupyterhub.ServiceName to match what we have setup in jupyterhub.hub.services

dask-gateway:
  gateway:
    auth:
      jupyterhub:
        jupyterhubServiceName: dask-gateway

2. Grant access:services!service=dask-gateway to the relevant group, as agreed with earthscope
3. Add that same scope to c.Spawner.server_token_scopes

Definition of Done

• Only the members of the selected group can access dask-gateway

@GeorgianaElena is this still relevant? If so, do you feel we should move on it?

[GeorgianaElena]

Yes it's relevant. We're actually waiting for them to come up with the groups and then test this on the staging hub (where this feature is actually supported).

Will mark it as blocked actually. Thanks for flagging it.
