Load Balancer Config for Collector Gateway so all spans of different services reach to one particular collector only

[scarshad]

Hey Folks
I have a question on how we configure our Nginx-Ingress(Load Balancer) for our collector deployment using Kubernetes.

Setup: Assume we have multiple collector gateway and an ingress setup which is receiving the traces and sending them to the collector. (there are n collectors which are running)
Go Service ---trace--> Ingress --> collector gateway --> DB (No Collector Agent in the picture)

Problem: How do you guys setup the Ingress config so that collector gateway pod-4(assume an instance) will receive all the spans of single particular trace. (In one trace there can be multiple service spans which can be present in the different cluster too).
