Imported service not respective topology awareness hints

[techmouse84]

Tested in EKS 1.24

Verified with the following setup . curling the imported service from an ubuntu pod will show that it's randomly distributed across the 2 pods. Expects imported service to respect topology awareness and hits only 1 pod.

apiVersion: apps/v1
kind: Deployment

  namespace: monitoring

Hello techmouse84 - We do not support Topology Aware Hints yet. Even mcs spec references the deprecated Topology API. We can definitely have a look into integrating in future milestones.
