Fitbit's Web API is being sunset and replaced by the Google Health API. Add support for the Google OAuth flow so users can authorize via Google OAuth instead of Fitbit's.
Migration strategy: When a user is linked to the Google Health source, if the same user already exists in the Fitbit source, a cascading delete is triggered to remove their Fitbit authorization upon successful Google OAuth completion.
