KubeletConfiguration is now always set to "systemd" unless the user is explicit about it. This requires existing machine setups to configure the container runtime to use the "systemd" driver. Documentation on this topic can be found here: https://kubernetes.io/docs/setup/production-environment/container-runtimes/. When upgrading existing clusters / nodes using "kubeadm upgrade" the old cgroupDriver value is preserved, but in 1.22 this change will also apply to "upgrade". For more information on migrating to the "systemd"...

production clusters efficiently. kubeadm has promoted high availability (HA) capability to beta, allowing users to use the familiar `kubeadm init` and `kubeadm join` commands to [configure and deploy an HA control plane](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability/). An entire new test suite has been created specifically for ensuring these features will stay stable over time.

Certificate management has become more robust in 1.15, with kubeadm...

- kubeadm: fix "certificate-authority" files not being pre-loaded when using file discovery ([#80966](https://github.com/kubernetes/kubernetes/pull/80966), [@neolit123](https://github.com/neolit123))
- Add instruction to setup "Application Default Credentials" to run GCE Windows e2e tests locally. ([#81337](https://github.com/kubernetes/kubernetes/pull/81337), [@YangLu1031](https://github.com/YangLu1031))

- Remove ready file and its directory (which is created during volume SetUp) during emptyDir volume TearDown. ([#95770](https://github.com/kubernetes/kubernetes/pull/95770), [@jingxu97](https://github.com/jingxu97)) [SIG Storage]

### Other (Cleanup or Flake)

- Kubelet: The `--azure-container-registry-config` flag has been deprecated and will be removed in a future release, please use `--image-credential-provider-config` and `--image-credential-provider-bin-dir` to setup acr credential provider instead.
