Suggestion: Automate logins

[carlmes]

In the instructions for notebooks we have the following:

auth = TokenAuthentication(
    token = "sha256~M1oYD5GM1mAXDrDCWPhXoGU2vEnwktp79JEhAvmS4Xo",
    server = "https://api.cluster-clplg.dynamic.redhatworkshops.io:6443",
    skip_tls=True
)
auth.login()

Can we make this better, for example by using environment variables to send this information down into the pod rather than manually copy pasting which is prone to mistakes, and the token expiring after a period of time?
