Backwards Incompatible Changes

• Unique name for prometheus TopN metric https://github.com/ns1labs/pktvisor/pull/183

The "name" label on Top N metrics in Prometheus output has changed to be domain specific - for example dns_top_qname2{instance="gw",name=".aaplimg.com"} is now dns_top_qname2{instance="gw",qname=".aaplimg.com"} and dns_top_rcode{instance="gw",name="NOERROR"} is now dns_top_rcode{instance="gw",rcode="NOERROR"}. Please update your dashboards accordingly, or use the latest community dashboard.
