[IMP] hw_drivers: Adds the ability to listen to a port

With this commit it is now possible for the IoT Box
to listen on a specific port of the box to interact
with a device via TCP / IP.

We use the library 'socket' to listen on port 9000
and if a request comes on this port we create an IoT Device
