  ///
  /// - Parameters:
  ///   - methodConfiguration: Method specific configuration used by the client transport to
  ///       determine how RPCs should be executed.
  ///   - retryThrottle: The retry throttle the client transport uses to determine whether a call
  ///       should be retried.
  /// - Returns: A tuple containing the connected server and client in-process transports.
