kubeadm: revert feature to backup kubelet config for "upgrade node"

Browse Source 
There seems to be a bug where it's not possible to write to
/etc/kubernetes/tmp... at the time of backing up the old kubelet
config.yaml

Also this kubelet config backup only targets "upgrade node"
and it should also target "upgrade apply".

Revert the related changes until a fully working feature
is implemented.
