only 1 rke-machine-config object is created when using provisioning/rke2k3s automation (but we should have 1 per pool instead)

the behavior I'm seeing is, on a completely healthy cluster with say 3 pools, one for etcd, one for controlplane and one for worker, scaling the worker pool ends up scaling the etcd pool instead
