Andre Heinecke 382d68ff8e Use secrets service for cups auth_info
When a printer requires auth_info (e.g. a printer connected
    over the samba protocol) it is now possible to save the
    credentials necessary for printing if a secrets service
    is available over dbus.
    The auth_info is then stored / loaded from the default
    collection of that secrets service.
    If no such service is available the user is not shown
    the option to remember the password and the behavior
    remains the same as before.
