Do you think it would be helpful to add some validation here for when traffic distribution has an unsupported value?

My worry would be if k8s supports extra values in the future we have to also update it here and the failure mode even if we errored here is the same as the operator failing to sync a service manifest (it won't update the svc and logs errors)

We currently allowing setting topology aware routing (an annotation on services) to reduce cross AZ traffic, but this has lots of limitations and only works for deployments with lots of pods.
Instead lets allow the use of traffic distribution so we can configure service traffic to prefer (but fail back to not) traffic to stay with AZs - this means pods routing to the service of gateways will try and keep within AZ boundaries hopefully reducing cross AZ traffic.
