Extend NetworkDnsEventReported and add new DnsCallReported to log per-query information

NetworkDnsEventReported -The message represents the entire lookup operation,
which may result one or more queries to the recursive DNS resolvers.

DnsCallReported - Those DNS queries are individually logged in DnsCallReported
to enable computing error rates and network latency and timeouts broken up by
query type, transport, network interface, etc

Test: make statsd_testdrive
     ./out/host/linux-x86/bin/statsd_testdrive 116 => pass
