	// option you choose:
	//   - None – Amazon EKS doesn't change the value. The update might fail.
	//   - Overwrite – Amazon EKS overwrites the changed value back to the Amazon EKS
	//   default value.
	//   - Preserve – Amazon EKS preserves the value. If you choose this option, we
	//   recommend that you test any field and value changes on a non-production cluster
	//   before updating the add-on on your production cluster.

	// permissions assigned to the node IAM role. For more information, see Amazon EKS
	// node IAM role (https://docs.aws.amazon.com/eks/latest/userguide/create-node-role.html)
	// in the Amazon EKS User Guide. To specify an existing IAM role, you must have an
