Issue:
Add China-based STUN servers
### Feature description

Let's extend our default STUN server list with a service operating in China.

### Problem or use case

Our default list of STUN servers lacks services located in China. As the other servers may not be reachable through the Great Firewall, this may reduce the connectivity of our Chinese users.

### Alternatives or workarounds

We could stick with our current list and hope that some of them are reachable.


Discussion / hints:
Possible candidates:

* `stun.miwifi:3478` (Xiaomi, Mainland IP)
* `stun.hitv.com:3478` (MangoTV, Mainland IP)
