node: Add port_info event
Add a port_info event. With this, we get updates to ports pushed to us, which is more convenient and also allows for better dynamic add/remove of ports. We don't need to the PortChanged event anymore We can remove the get_port_ids/get_n_ports/port_get_info methods. Update plugins
