The label kamaji.clastix.io/soot is deprecated in favour of
kamaji.clastix.io/name, every external resource referring to this must
be aligned prior to updating to this version.
Starting from this change, all the nodes trying to join a Kamaji TCP
must be initiated with kubeadm >= 1.25. This is not a hard-prerequisite
since a previous Kubernetes version can be used by specifying it in the
ClusterConfiguration kubernetesVersion field.
