Adds a parameter is_automatic to the method CupsPrintersManager::PrinterInstalled

Inside the method mentioned above we were not able to distinguish
between manual and automatic printer installation. As a result in both
cases the event metrics::PrinterEventProto::SETUP_MANUAL was reported
and the event metrics::PrinterEventProto::SETUP_AUTOMATIC has never
appeared in logs. To solve this problem I have added bool parameter
is_automatic to the method that carries information about a type of
printer installation. It allows to distinguish between these two cases
and report a correct event.
