Currently, one may not be able to differentiate between a query refusal
by the target and the target not responding to a query. These two cases
can have very different ramifications.
This patch adds the probe_dns_query_succeeded gauge which is 1 if and
only if the DNS query was executed correctly, i.e., that the target
host has sent a response, and 0 otherwise.
Resolves #474
