VOL-766 openOLT disable and reenable with propagation to child devices.
This is a soft disable which disables the ports and then the flows. It
sets the OLT and it's child devices to AdminState.DISABLED,
OperStatus.UNKNOWN, and ConnectStatus.UNREACHABLE. It includes a
reenable that reverses the effect.
