Proxying websocket connections (e.g. /ws/logs)

[cdjackson]

I assume that the cloud service doesn't currently proxy OH websockets? Now that we have an embedded log viewer in the main UI, it would be super useful if OH websocket connections were also proxied by the cloud connector. I've not looked at this repo at all so am not sure what's involved, but thought I'd raise this now that the log viewer is merged since I suspect there will be similar questions once 4.3 is released...

#447 might already provide what’s needed.
