- Add a `serving` and `terminating` condition to the EndpointSlice API.
  `serving` tracks the readiness of endpoints regardless of their terminating state. This is distinct from `ready` since `ready` is only true when pods are not terminating. 

- The kube-controller-manager managed signers can now have distinct signing certificates and keys.  See the help about `--cluster-signing-[signer-name]-{cert,key}-file`.  `--cluster-signing-{cert,key}-file` is still the default.

- Kubectl: Graduated kuberc support to beta. A `kuberc` configuration file provided a mechanism for customizing `kubectl` behavior (distinct from kubeconfig, which configures cluster access across different clients).
