Hi guys, is it possible to use

resource "rancher2_cluster_v2" "external-cloud-provider" {
  name = "external-cloud-provider"
    machine_selector_config {
      config = {
        cloud-provider-name = "external"
      }

and install a custom cloud provider (openstack cloud controller manager) via a helm chart in the terraform config? I saw examples for harvester cloud provider but that seems to be an included chart?
