OutboundPacket: add inPort method
Allows to provide a different input port to be considered when emitting
the packet. It is useful on OpenFlow devices so one can use ALL or FLOOD
actions as output and not have the packet sent back on the input port.
Default is controller port, as it was before.
The required changes were also implemented in OpenFlowPacketProvider
