changes lgtm, also confirmed it fixes the istio integration test error istio/istio#45900 (comment)
Currently, if a DNS request is forwarded to the upstream resolver and fails with NXDomain, the client will see a successful response with no records. This is due to the fact that the DNS system forwarder returns an error of type ResolveError, which was not being handled properly by the Handler. This fixes the logic and adds tests for the system forwarder. Fixes istio#600
