Kubernetes upgrade control-plane step was failing due to kubeadm not
accepting the format of the empty kubelet_override.yaml file. This file
minimally requires the apiVersion to be specified even if there are no
actual overrides.
This adds apiVersion to the kubelet_override.yaml file.
Test Plan:
PASS: Kubernetes 1.23.1 to 1.24.4 upgrade
PASS: Manually call kubeadm upgrade apply v1.24.4 same as:
system kube-host-upgrade controller-0 control-plane
