    1. following the documentation from here fails :
https://github.com/stolostron/rhacm-docs/blob/2.9_stage/clusters/hosted_control_planes/scale_nodepool_hosted_bm.adoc#adding-node-pools

    2.(.venv) [kni@ocp-edge77 ocp-edge-auto_cluster]$ hcp create nodepool agent   --cluster-name $CLUSTER_NAME   --name $NODEPOOL_NAME   --node-count $WORKER_COUNT 

    we see it fails for :
  3.    spec.management.upgradeType: Unsupported value: "": supported values: "Replace", "InPlace"

   This syntax seems to do the trick :

(.venv) [kni@ocp-edge77 ocp-edge-auto_cluster]$ hcp create nodepool agent   --cluster-name $CLUSTER_NAME   --name $NODEPOOL_NAME   --node-count $WORKER_COUNT --node-upgrade-type Replace
