fqdn: Timeouts in forwarded DNS Proxy passed back
fqdn: Timeouts in forwarded DNS Proxy passed back

A timeout when forwarding a DNS lookup triggers an error in the proxy,
but we intend to emulate what the original requester would see. Thus,
we now do nothing and let them timeout.
This is motivated by how we handle errors with proxies. If we report
timeouts as errors, they increment l7_proxy_parse_errors and that is
misleading.
