### One-sentence description Synchronise activemembers with G Suite ### Motivation Because then we can migrate to Google Drive instead of Thalia Cloud. ### Desired functionality Sync of member email addresses according to the `is_staff` status. ### Suggested implementation Use signals to find out when users are changed - They get `is_staff` = create account - `is_staff` removed = remove account - username is changed and they are `is_staff` = update account
