Enabling DNS Filter Support for Custom Domain Upstream

[cxplay]

Issue Details

dnsproxy, which is now widely available in AdGuard products, supports specifying specific DNS upstream servers for each domain in a configuration file.

• https://github.com/AdguardTeam/dnsproxy#specifying-upstreams-for-domains
• https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration#upstreams-for-domains

But this feature does not work with regular DNS filters, so you must run a DNS proxy server locally to split the traffic to the upstream servers.

Proposed solution

Make the DNS filter syntax support specifying upstream resolving servers.
