DnsServer: implemented ResolverDnsCache for recursive resolution. Updated ProcessQuery() to change the sequence of checking for blocked zones to allow blocking correctly in case of stub zone or forwarder zone being used. Fixed implementation changes in ProcessAuthoritativeQuery(), ProcessCNAME(), ProcessANAME() and ProcessRecursiveQuery(). RecursiveResolveAsync() stopped caching failure record in case of exception due to undesirable side effects for clients. CachePrefetchSamplingAsync() added zone type checks. Code refactoring done.
