During kubeadm join in 1.30 kubeadm started respecting the kubeletconfiguration healthz address/port. Previously it hardcoded the health check to localhost:defaultport. A corner case was not handled where the user applies --patches on join to modify the local kubeletconfiguration. This results in kubeletconfiguration patch target patches not being applied to the KubeletConfiguration in memory and the health check running on the address:port which are present in the kubelet-config configmap. Fix that by explicitly calling a new function to patch the KubeletConfiguration in memory. This is scoped to only handle the healthz checks *after* the kubelet config.yaml was already patched and written to disk.
