    worker: give hint about password expiration
    
    When you run "passwd -f (username)" to expire a users password, and then try to
    login via GDM the following happens:
    
    - user enters their username
    - user enters their password
    - The dialog prompt says "New password"
    - The user enters a new password
    - The dialog prompt says "Enter password again"
    - The user enters the same password, changes their password and their session
      starts.
    
    Some of our users were confused why the dialog was asking for a new password.
    
    This commit adds code to show the user a message explaining that the user
    needs to enter their new password.
