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.
This is definitely a scenario we want to support in the future.
