Apply tf_upgrade_v2 for output_template

[ytfksw]

What this patch does to fix the issue.

I have realized that output_template has a python file using TensorFlow (output_template/python/lmnet/tensorflow_graph_runner.py)

This patch makes output_template/python/lmnet/tensorflow_graph_runner.py compatible with tf2

Here's what I did:

1. install newest tenosrflow (tensorflow-gpu==1.5.2)
2. Run the upgrade script tf_upgrade_v2 for output_template
3. Check the upgrade report for warnings and errors
4. Run test (make test)

Link to any relevant issues or pull requests.

• Consider upgrading to TensorFlow 2.0 #479
• https://www.tensorflow.org/guide/upgrade

[ytfksw]

We got 2 warnings about keras.model.save

WARNING: *.save requires manual check. (This warning is only applicable if the code saves a tf.Keras model) Keras model.save now saves to the Tensorflow SavedModel format by default, instead of HDF5. To continue saving to HDF5, add the argument save_format='h5' to the save() function.

Since we don't use Keras.model now, it is irrelevant.

Actually, we call PIL.Image.Image.save:
