[CRD Mobile] No IPv6 STUN/TURN Support

Project Member Reported by yuweih@chromium.org, Jan 29 2018 
STUN and TURN support is needed under restricted network condition. However, currently there is no STUN or TURN server on Chromotocol that supports IPv6. User will not be able to connect if they are under IPv6-only network (NAT64/DNS64), and their host doesn't accept direct connection from the client.

WebRTC does provide STUN and TURN support for IPv6. Given that our long term goal is to migrate to WebRTC on mobile clients, this should be fixed once the migration is done.

Changing the priority, as we are seeing many more people hitting into this issue on the iOS app.

Some people claim it works on the old app, so it's could be changes in port allocation logic that broke it. This is currently not reproducible as we don't have NAT64/DNS64 infrastructure on campus.

WebRTC connection works on IPv6-only environment even without 6to4 translation, so switching to use WebRTC will fix this problem. However, it's probably still too early to switch to WebRTC right now.
