resolved: cache - cache what we can of negative redirect chains
When a NXDATA or a NODATA response is received for an alias it may include CNAME records from the redirect chain. We should cache the response for each of these names to avoid needless roundtrips in the future. It is not sufficient to do the negative caching only for the canonical name, as the included redirection chain is not guaranteed to be complete. In fact, only the final CNAME record from the chain is guaranteed to be included. We take care not to cache entries that redirects outside the current zone, as the SOA will then not be valid.
