First draft of inventory service connectors, and service implementation. No handlers yet, this is just the OUT part for now. It's not active and nothing in the simulator uses this yet. Just checking it in to start sharing with others. There are a couple of interesting software design points that could use other devs opinions.
Hopefully I added all needed files.
