DoH proxy: https-dns-proxy new RFC8484-supporting package and Web UI

@stangri I try to test the newest r1 build although I currently have an issue with dnsmasq that I can’t resolve at the moment. The domain resolving is really slow sometimes or doesn’t work at all.

Anyway I tried to stop https-dns-proxy to see if that will help with dnsmasq issue. It didn’t but I found out that when I stop https-dns-proxy it didn’t restore the dnsmasq settings.

Those are still there.

Edit - my latest findings show that currently maybe both pbr and https-dns-proxy caused the dnsmasq issues at least on my hardware with my settings.

Update 2 - I’ve enabled https-dns-proxy again (pbr remains disabled) to try it alone.

No issues with it currently, dnsmasq working OK, no high CPU usage, nor errors in the log.
