OnRequestDeviceOnUI. "'normal method name'OnUI" is a common short suffix pattern
that I think we should use.

   void OnSetBluetoothMockDataSetForTesting(const std::string& name);
 
   // A BluetoothAdapter instance representing an adapter of the system.
   scoped_refptr<device::BluetoothAdapter> adapter_;
 
   enum class MockData { NOT_MOCKING, REJECT, RESOLVE };
   MockData bluetooth_mock_data_set_;
   BluetoothError bluetooth_request_device_reject_type_;
 
   DISALLOW_COPY_AND_ASSIGN(BluetoothDispatcherHost);
