Add support for Bunny.net's new Bunny DNS service

[d19dotca]

It looks like Bunny.net (the awesome CDN) is entering the world of DNS hosting! Would love to see support for this added to Cloudron once it's ready.

Their blog post about it is here: https://bunny.net/blog/transforming-internet-routing-introducing-bunny-dns/

A public preview is expected in April 2022 (currently private beta until then). It will also be free to use (unless using their scripting too).

Were you one of the lucky ones that got picked? I'm still waiting for my spot to open up.

@humptydumpty Unfortunately not

@humptydumpty Just got the invite the other week by the way, but haven't started using it yet, will probably run it through some paces next week sometime.

@d19dotca That's great! Please do report back!

Edit: BTW, please take some speed tests if you can. I posted some results here if you want to compare notes: https://forum.cloudron.io/topic/7190/dns-speed-comparison-dnsmadeeasy-vs-digitalocean-vs-cloudflare-averaged?_=1659930130113

I used DNSPerf for the tests: https://www.dnsperf.com/dns-speed-benchmark/
