Replaces a worker pool’s node labels and taints. Send both lists: a list you leave out is cleared. The changes apply to the pool’s existing nodes in place, and no node is replaced; running pods are affected only by NoExecute taints.

The pool must be ready, and the cluster ready or worker_joined. Pods use the full key, for example a nodeSelector of node.e2enetworks.com/team: ml.
