kubeadm: remove the usage of the --container-runtime=remote flag for the kubelet during kubeadm init/join/upgrade. The flag value "remote" has been the only possible value since dockershim was removed from the kubelet.

this is fine but during upgrade, we also have to mutate the kubeadm flags file /var/lib/kubelet/kubeadm-flags.env to remove this flag.

we did something similar when we did the migration from sockets without URL scheme if you remember.

Updated. And find the updateKubeletDynamicEnvFileWithURLScheme is not cleanup.
