/**
 * Manages long-running operations with an API service.
 *
 * When an API method normally takes long time to complete, it can be designed
 * to return [Operation][google.longrunning.Operation] to the client, and the client can use this
 * interface to receive the real response asynchronously by polling the
 * operation resource, or pass the operation resource to another API (such as
 * Google Cloud Pub/Sub API) to receive the response.  Any API service that
 * returns long-running operations should implement the `Operations` interface
 * so developers can have a consistent client experience.
