Change controller+worker taints label to `node-role.kubernetes.io/control-plane`

[walf443]

Is your feature request related to a problem? Please describe.

k0s taints "controler+worker" node as node-role.kubernetes.io/master by default.

The node label node-role.kubernetes.io/master was already deprecated. https://kubernetes.io/docs/reference/labels-annotations-taints/#node-role-kubernetes-io-master-taint

For workloads intended to run solely on control plane nodes, users often rely on the presence of this label. To better facilitate this use case, it would be beneficial I think if nodes designated as control plane nodes were automatically tainted with node-role.kubernetes.io/control-plane by default.

For example, I got this issue with topolvm scheduler settings: https://github.com/topolvm/topolvm/tree/main/charts/topolvm scheduler.affinity

Describe the solution you would like

Given that this change could potentially impact backward compatibility in long-running clusters, perhaps it would be more prudent to introduce it around v1.34.0+k0s or v1.35.0+k0s ? This would allow existing clusters more time to adapt.

Describe alternatives you've considered
