Andrey Smirnov	c4fb7dad0e	fix: force DNS runner shutdown on timeout ... I observed a random failure (via Sidero Metal integration tests) when Talos fails to reboot due to the runner never shutting down. A probable root cause is a bug in the `dns` library (which runs the NDS server), but we need to ensure this code always terminates, even at the price of leaking a running DNS server.

Dmitriy Matrenichev	4fe6dc8a0a	chore: clean dns code ... Split from #9596 (without IPv6 stuff). This PR does this things: - Refactored `DNSResolveCacheController`. Most of the logic moved to `dns` package types. Simplify and streamline logic. - Replace most of the goroutine orchestration with suture package. - Support per-item reaction to the dns listeners/servers failing to start. This allows us to ignore IPv6 errors if it's disabled. - Support per-item reaction to the dns listeners/servers failing to stop.
