示例1: Authorize
// Authorize makes a REST request to the remote service describing the attempted action as a JSON
// serialized api.authorization.v1beta1.SubjectAccessReview object. An example request body is
// provided bellow.
//
// {
// "apiVersion": "authorization.k8s.io/v1beta1",
// "kind": "SubjectAccessReview",
// "spec": {
// "resourceAttributes": {
// "namespace": "kittensandponies",
// "verb": "GET",
// "group": "group3",
// "resource": "pods"
// },
// "user": "jane",
// "group": [
// "group1",
// "group2"
// ]
// }
// }
//
// The remote service is expected to fill the SubjectAccessReviewStatus field to either allow or
// disallow access. A permissive response would return:
//
// {
// "apiVersion": "authorization.k8s.io/v1beta1",
// "kind": "SubjectAccessReview",
// "status": {
// "allowed": true
// }
// }
//
// To disallow access, the remote service would return:
//
// {
// "apiVersion": "authorization.k8s.io/v1beta1",
// "kind": "SubjectAccessReview",
// "status": {
// "allowed": false,
// "reason": "user does not have read access to the namespace"
// }
// }
