### Promoted endPort in Network Policy to Stable

Promoted `endPort` in [Network Policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/#targeting-a-range-of-ports) to GA. Network Policy providers that support `endPort` field now can use it to specify a range of ports to apply a Network Policy. Previously, each Network Policy could only target a single port.

### Other (Cleanup or Flake)

- Updates konnectivity-network-proxy to v0.0.27. This includes a memory leak fix for the network proxy ([#107037](https://github.com/kubernetes/kubernetes/pull/107037), [@jdnurme](https://github.com/jdnurme)) [SIG API Machinery, Auth and Cloud Provider]

### Changed
- sigs.k8s.io/apiserver-network-proxy/konnectivity-client: v0.0.25 → v0.0.27

The merged fix enforces validation against the proxying address for a Node. In some cases, the fix can break clients that depend on the `nodes/proxy` subresource, specifically if a kubelet advertises a localhost or link-local address to the Kubernetes control plane. Configuring an egress proxy for egress to the cluster network can also mitigate this vulnerability.

**Affected Versions**:

- Service session affinity timeout tests are no longer required for Kubernetes network plugin conformance due to variations in existing implementations. New conformance tests will be developed to better express conformance in future releases.

- Fixes a problem with 63-second or 1-second connection delays with some VXLAN-based
  network plugins which was first widely noticed in 1.16 (though some users saw it
  earlier than that, possibly only with specific network plugins). If you were previously
  using ethtool to disable checksum offload on your primary network interface, you should

### Bug or Regression

- An inefficient lock in EndpointSlice controller metrics cache has been reworked. Network programming latency may be significantly reduced in certain scenarios, especially in clusters with a large number of Services.
