Get GPS PoC to run unprivileged about examples

[t-fine]

I moved this into the "In Progress" column because this became an issue with updates to horizon and running privileged containers, but we are bypassing this at the moment by updating the node policy when registering with the cpu2evtstreams pattern

I think you'll need to work with the anax team to have them add whatever options they need to when making their docker api call to start the container when the devices field is specified in the deployment field.

You might have to put together a small test service that shows that docker run --device=... does this. See https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities

I figured it out! Will share more details in scrum tomorrow, but here's the device mapping argument that allowed me to access the GPS device without "privileged": true, (wanna do a little more testing though)

"devices": [ "/dev/ttyACM0:/dev/ttyACM0" ]
