dns: add options to control automatic addition of edns0 and trust-ad

Beniamino Galvani requested to merge bg/dns-options-skip into main


Introduce new options _skip-edns0 and _skip-trust-ad to prevent the automatic addition of edns0 and trust-ad when using caching plugins. The initial underscore indicates that the option is internal and is not written into resolv.conf.


Options edns0 and trust-ad are automatically added when using caching plugins such as dnsmasq and systemd-resolved. In some cases, those options can break resolution due to non-conforming resolvers, and there is no way to disable them. This MR provides a solution to that problem, reported in #1393 (closed)

I couldn't find any better names for the options, suggestions are welcome.
