`ClusterConfiguration.Etcd.ExternalEtcd` that can be used to configure the HTTP endpoints for etcd communication in v1beta4. This field is used to separate the HTTP traffic (such as /metrics and /health endpoints) from the gRPC traffic handled by Endpoints. This separation allows for better access control, as HTTP endpoints can be exposed without exposing the primary gRPC interface. Corresponds to etcd's `--listen-client-http-urls` configuration. If not provided, Endpoints will be used for both gRPC and HTTP traffic....

#### Additional Notable Feature Updates
- Support for go modules in Kubernetes Core.
- Continued preparation for cloud provider extraction and code organization.  The cloud provider code has been moved to kubernetes/legacy-cloud-providers for easier removal later and external consumption.

server-side printing and its support in kubectl, as well as finishing [kubectl diff which is based on server-side dry-run feature](https://kubernetes.io/docs/concepts/overview/working-with-objects/object-management/#how-to-create-objects). We’ve continued separating kubectl code to prepare for extraction out of main repository. Finally, thanks to the awesome support and feedback from community we’ve managed to promote the new [plugin mechanism to Beta](https://kubernetes.io/docs/tasks/extend-kubectl/kubectl-plugins/)....

### Other (Cleanup or Flake)

- "Removed the ability to run `kubectl exec [POD] [COMMAND]` without a `--` separator.
  The `--` separator has been recommended since the Kubernetes v1.18 release, which also deprecated the legacy way of invoking `kubectl exec`.
  

- Pod SecurityContext and PodSecurityPolicy supports slash as sysctl separator. ([#106834](https://github.com/kubernetes/kubernetes/pull/106834), [@mengjiao-liu](https://github.com/mengjiao-liu)) [SIG Apps, Architecture, Auth, Node, Security and Testing]
