+//
+// Istio RBAC (Role Based Access Control) defines ServiceRole and ServiceRoleBinding
+// objects.
+//
+// A ServiceRole specification includes a list of rules (permissions). Each rule has
+// the following standard fields:
+//
+//   * services: a list of services.
+//   * methods: A list of HTTP methods. You can set the value to `\*` to include all HTTP methods.
+//              This field should not be set for TCP services. The policy will be ignored.
+//              For gRPC services, only `POST` is allowed; other methods will result in denying services.
+//   * paths: HTTP paths or gRPC methods. Note that gRPC methods should be
+//     presented in the form of "/packageName.serviceName/methodName" and are case sensitive.
+//
+// In addition to the standard fields, operators can also use custom keys in the `constraints` field,
+// the supported keys are listed in the "constraints and properties" page.
+//
+// Below is an example of ServiceRole object "product-viewer", which has "read" ("GET" and "HEAD")
+// access to "products.svc.cluster.local" service at versions "v1" and "v2". "path" is not specified,
+// so it applies to any path in the service.
+//
+// ```yaml
+// apiVersion: "rbac.istio.io/v1alpha1"
+// kind: ServiceRole
+// metadata:
+//   name: products-viewer
+//   namespace: default
+// spec:
+//   rules:
+//   - services: ["products.svc.cluster.local"]
+//     methods: ["GET", "HEAD"]
+//     constraints:
+//     - key: "destination.labels[version]"
+//       values: ["v1", "v2"]
+// ```
+//
+// A ServiceRoleBinding specification includes two parts:
+//
+//  * The `roleRef` field that refers to a ServiceRole object in the same namespace.
+//  * A list of `subjects` that are assigned the roles.
+//
+// In addition to a simple `user` field, operators can also use custom keys in the `properties` field,
+// the supported keys are listed in the "constraints and properties" page.
+//
+// Below is an example of ServiceRoleBinding object "test-binding-products", which binds two subjects
+// to ServiceRole "product-viewer":
+//
+//   * User "alice@yahoo.com"
+//   * Services in "abc" namespace.
+//
+// ```yaml
+// apiVersion: "rbac.istio.io/v1alpha1"
+// kind: ServiceRoleBinding
+// metadata:
+//   name: test-binding-products
+//   namespace: default
+// spec:
+//   subjects:
+//   - user: alice@yahoo.com
+//   - properties:
+//       source.namespace: "abc"
+//   roleRef:
+//     kind: ServiceRole
+//     name: "products-viewer"
+// ```
