HCP is missing feature parity from rosa_classic - Some required attributes cannot be set.

[InfoSec812]

For provisioning a new cluster using hosted control-planes (HCP) the following parameters which are available in classic are not available in HCP:

  aws_additional_compute_security_group_ids = [module.portworx_sg.portworx_sg_id]
  default_mp_labels                         = var.compute_machine_labels
  autoscaling_enabled                       = local.autoscaling
  min_replicas                              = local.autoscaling ? local.replicas : null
  max_replicas                              = local.autoscaling ? var.max_replicas : null
  admin_credentials = {
    password = var.admin_password
    username = local.admin_username
  }

The admin_credentials along with create_admin_user being true works form me for rhcs_cluster_rosa_hcp resource with terraform-redhat/rhcs v1.6.6
