Description

What problem are you trying to solve?

Too often AGH breaks affiliate links. There are legitimate use cases such as order confirmation emails, etc. Affiliate links/domains shouldn't be blocked in general as they come into play only when clicked on.

Proposed solution

Provide an out of the box AGH allow list for affiliate links, similar to https://raw.githubusercontent.com/nextdns/metadata/master/privacy/affiliate-tracking-domains Note that the above needs to be converted to AGH format to also include subdomains.

Alternatives considered

Adding https://raw.githubusercontent.com/nextdns/metadata/master/privacy/affiliate-tracking-domains directly, but it doesn't work well because its syntax doesn't include subdomains.

Additional information

There's a related request here but it's lost in the noise https://github.com/AdguardTeam/AdGuardHome/issues/1913#issuecomment-949736331

We should track this issue as it's pretty important.
