Idea: Replace DNS feature with CoreDNS

[fipso]

The current DNS implementation lacks:

• Automatic Let's Encrypt ACME
• Stability

Because I want to keep stuff simple and dont reinvent the wheel I am thinking about dropping the DNS feature from freenews and instead do one of the following:

• Build a CoreDNS plugin
• Generate a CoreDNS Corefile from code
• Use some other DNS lib
• (Fix my own DNS code and add features I want)

... add more reasons to switch to coreDNS

Core DNS Features:

• Plugin API
• DoT
• DoH
• DNS over Quic
• DNS over gRPC
• dns forwarding

I also think integrating other DNS MITM based services like PiHole/AdGuard is way easier with CoreDNS
