Idea: LGTM Services: trafficDistribution - PreferClose

[NathanH05]

What is the problem you are trying to solve?

Cross-AZ traffic is very expensive at scale between Loki, Mimir and Tempo components in our EKS cluster.

Which solution do you envision (roughly)?

K8s 1.31 includes a trafficDistribution feature where you can set PreferClose so that topologically requests on services can jump to the nearest pod, this can mean requests remain even on the same node rather than incurring expensive cross availability zone traffic costs in AWS or other cloud providers.

Have you considered any alternatives?
