remove console flow authentication method

[lavigne958]

Overview

as mentioned in #1032 the authentication flow using console_flow has been deprecated by google and should be removed.

Any code related to it can be removed, we can update the dependency google-auth-oauthlib

This is a major change (even though people using it are already blocked due to the API beeing disabled) we must remove this part in a major release.

Update our dependencies on the way:

• google-auth
• google-auth-oauthlib
