Dual Dispatching of Lookups

Hi, I'm really strongly considering using this in my cluster but ideally would like it to dispatch out to multiple servers and use the first response for fast resolution.

I don't mind forking this project and adding it if its not in your roadmap.

My question is: where would be the best spot to hook this functionality in?

I'm looking for an alternative to https://github.com/dcos/spartan . Spartan is in Erlang and not easy to install

Hi, i think this would make a great PR. It should be implemented as a configurable option though because go-dnsmasq should replicate glibc's resolver behavior by default (implementing the primary/secondary nameserver principle). The best place to hook this in would be the forwardQuery func https://github.com/janeczku/go-dnsmasq/blob/master/server/forwarding.go#L224. We could do a forwarder interface but i don't think it's necessary. Just add a forwardQueryParallel func and put your logic in there.
