This PR adds a new controller - `DNSServerController` that starts tcp and udp dns servers locally. Just like `EtcFileController` it monitors `ResolverStatusType` and updates the list of destinations from there. Most of the caching logic is in our "lobotomized" "`CoreDNS` fork. We need this fork because default `CoreDNS` carries full Caddy server and various other modules that we don't need in Talos. On our side we implement random selection of the actual dns and request forwarding. Closes #7693 Signed-off-by: Dmitriy Matrenichev <dmitry.matrenichev@siderolabs.com>
