- Kubeadm: warn but do not error out on missing "ca.key" files for root CA, front-proxy CA and etcd CA, during "kubeadm join --control-plane" if the user has provided all certificates, keys and kubeconfig files which require signing with the given CA keys.

### Other (Cleanup or Flake)

- Kube-apiserver: Promoted the `ExternalServiceAccountTokenSigner` feature to beta, which enabled external signing of service account tokens and fetching of public verifying keys. This was accomplished by enabling the beta `ExternalServiceAccountTokenSigner` feature gate and specifying the `--service-account-signing-endpoint` flag. The flag value could either be the path to a Unix domain socket on the filesystem, or be prefixed with @ to indicate a Unix domain...

### kubectl
* Running `kubectl taint` (alpha in 1.5) against a 1.6 server requires upgrading kubectl to version 1.6
* Running `kubectl taint` (alpha in 1.5) against a 1.5 server requires a kubectl version of 1.5
* Running `kubectl create secret` no longer accepts passing multiple values to a single --from-literal flag using comma separation

* Make ConfigMap volume readable as non-root ([#23793](https://github.com/kubernetes/kubernetes/pull/23793), [@pmorie](https://github.com/pmorie))
* only include running and pending pods in daemonset should place calculation ([#23929](https://github.com/kubernetes/kubernetes/pull/23929), [@mikedanese](https://github.com/mikedanese))
