          Example:
              >>> import dialogflow_v2
              >>>
              >>> client = dialogflow_v2.AgentsClient()
              >>>
              >>> parent = client.project_path('[PROJECT]')
              >>>
              >>> response = client.get_agent(parent)
  
          Args:
              parent (str): Required. The project that the agent to fetch is associated with.
                  Format: ``projects/<Project ID>``.
              retry (Optional[google.api_core.retry.Retry]):  A retry object used
                  to retry requests. If ``None`` is specified, requests will not
                  be retried.
              timeout (Optional[float]): The amount of time, in seconds, to wait
                  for the request to complete. Note that if ``retry`` is
                  specified, the timeout applies to each individual attempt.
              metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                  that is provided to the method.
  
          Returns:
              A :class:`~google.cloud.dialogflow_v2.types.Agent` instance.
  
          Raises:
              google.api_core.exceptions.GoogleAPICallError: If the request
                      failed for any reason.
              google.api_core.exceptions.RetryError: If the request failed due
                      to a retryable error and retry attempts failed.
              ValueError: If the parameters are invalid.
