1. Generate a `/var/lib/kubelet/instance-config.yaml` file to customize the `containerRuntimeEndpoint` field in per-node kubelet configurations.
    2. Remove the `kubeadm.alpha.kubernetes.io/cri-socket` annotation from nodes during upgrade operations.

**Affected Versions**:
  - kubelet <= v1.28.0
  - kubelet <= v1.27.4
  - kubelet <= v1.26.7
  - kubelet <= v1.25.12
  - kubelet <= v1.24.16

**Fixed Versions**:
  - kubelet v1.28.1
  - kubelet v1.27.5
  - kubelet v1.26.8
  - kubelet v1.25.13
  - kubelet v1.24.17

- kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap
  User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials ([#80676](https://github.com/kubernetes/kubernetes/pull/80676), [@fabriziopandini](https://github.com/fabriziopandini))
