nit: Should update the DNS_CONFIG_CHANGED description in net_log_event_types.h. 
Maybe just replace the documentation with a pointer to DnsConfig in
dns_config_service.h? Not sure how much value there is in duplicated the
documentation in the two files.  Does make it a little easier to look events in
general, but how often do people do that?

I replaced the primitives with

<other>: <See DnsConfig>

This breaks the convention in net_log_event_types.h. Let me know if it's ok.

   dict->SetInteger("num_hosts", hosts.size());
 
   return dict;
