In an hcp cluster, the node labels and taints are not getting applied to a machine pool using ROSA CLI.
We also observed that nodes and taints do exist on nodepools, but they don't get synced down to the worker nodes

3. oc get node ip-10-0-0-10.us-east-2.compute.internal -o json | jq '. | .spec.taints, .metadata.labels' | grep stateless

null    

    There should be the labels and taints applied

In CAPI logs, I don't see our labels is being mentioned
