Feature Request - Option to resolve IPs to hostnames via DNS in Netflow/Insight

[JulianSiS]

As the title says... it would be nice to have the option to resolve IPs to hostnames via DNS for the Netflow/Insight reporting.
See https://forum.opnsense.org/index.php?topic=3223.0

This would be an amazing feature, I was also looking on how to do this.

It needs https://github.com/opnsense/core/blob/master/src/opnsense/mvc/app/controllers/OPNsense/Diagnostics/Api/DnsController.php and 97be197

When reverse lookup is selected, the charts expands to full width, domain names tend to be longer then ip addresses which limits the visible addresses to only a few due to how nvd3 handles the legends.

All done, thanks!
