Use probe_dns_duration_seconds

This PR: grafana/synthetic-monitoring-agent#54 uses an updated version of blackbox_exporter that exposes a metric called "probe_dns_duration_seconds", which is the time it takes for DNS check to complete from connection to getting back the RR from the DNS server. The metric has a label "phase" with three different values for each phase of the query, just like probe_http_duration_seconds. Signed-off-by: Marcelo E. Magallon <[email protected]>
