Description

This PR fixes the UPnP status messages and allows the detection of UPnP iuds that are in status 2 (not connected)

An IGD in status 1 is the IGD of the network and connected (has an external IP which isn't in a private block)
An IGD in status 2 is also the IGD of the network but may not be connected due to various reasons (no external IP or external IP in a private IPv4/IPv6 block)

Sunshine should not discard an IGD of status 2 as the reason to the unconnected status is not determinable by an outside source and has to be fixed by the network administrator/owner. This can be a misconfigured second router or just the ISP being down due to various reasons.

We still do not attempt to open ports on a status 3 as this is just a UPnP device which is not an IGD.
