    Waits for the extended (long-running) operation to complete.

    If the operation is successful, it will return its result.
    If the operation ends with an error, an exception will be raised.

        operation: a long-running operation you want to wait on.
        verbose_name: (optional) a more verbose name of the operation,

        set for the `operation`.
