Hierarchy possibilities for edge devices.
The purpose is to have for example 5 incoming sensors in the 'sensor' edge device where we can do some calculations on the edge. The output goes to another edge device, where again we can do some calculations on the edge with input from other similar 'sensor' edge devices. The last edge device in the chain will send the data to the IoT Hub.

@Chipalo any update on this feature. It would provide a lot more flexibility. You could use a couple of the `sensor` edge's on constrained devices direct to IoTHub, but in a different installation multiple of them could be routed through a server to provide store and forward to take advantage of the IoTHub throttling.
