### Failing Test

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.

  - `service.kubernetes.io/topology-aware-hints` annotation has been deprecated.
  - kube-proxy now accepts any value that is not "disabled" for these annotations, enabling custom implementation-specific and/or future built-in heuristics to be used.
