Add Tencent Cloud DNS

[Mcszl]

It is suggested to add Tencent Cloud DNS (DNSpod) to adapt to more DNS environments.

@Mcszl Thanks for this suggestion. Any new providers are built by the open source community or the vendors (like Tencent). Would you like to contribute a provider for this? Or do you have contacts at Tencent that you could encourage to build a provider?

https://www.dnspod.com/?lang=en is the product I think you're talking about here. It is cool to see that it is a free service, so anyone that was interested in filing this gap could volunteer.
