Gets a single trace by its ID.

        Example:
            >>> from google.cloud import trace_v1
            >>>
            >>> client = trace_v1.TraceServiceClient()
            >>>

            >>> project_id = ''

            >>> # TODO: Initialize `trace_id`:
            >>> trace_id = ''
            >>>
            >>> response = client.get_trace(project_id, trace_id)

        Args:
            project_id (str): ID of the Cloud project where the trace data is stored.
            trace_id (str): ID of the trace to return.
            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.trace_v1.types.Trace` 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.
