Goldmane flows should include the source IP address

[andrenth]

It would be exceedingly useful if the Goldmane Flows API included a field for the source IP address in a flow, especially for traffic originating from public networks outside the cluster (for completeness, including the whole IP/port 4-tuple would probably be better).

Expected Behavior

The flows in the Goldmane API should include a source IP address field (and Whisker should have an option to display/filter based on it).

Current Behavior

There is no source IP information available at all.

Context

Identifying illegal or malicious inbound traffic would be made much easier with this feature.
