[RFE] Inspektor Gadget: Improve the way IP addreses are showed in the output

[blanquicet]

The way IP addresses are showed in the output of Inspektor Gadget can be improved to not simply show the raw IP, but use the Kubernetes resource when it is available:

Current situation:

Src                    Dst
10.244.1.15:8080       10.244.2.41:56466

Proposal:

Src                    Dst
p/default/pod-1:8080   p/default/pod-2:56466 

The logic to do it is available here.

So, this logic needs to be modified to take advantage of the whole data provided by Inspektor Gadget.
