mo_gaal Tensorflow -> Pytorch

[zhuox5]

I have tried to convert the mo_gaal model from Tensorflow to Pytorch. I didn't create a new test_mo_gaal.py because the original one works well.

In mo_gaal(Pytorch version), instead of keeping consistent with default hyper-parameter value as of the tensorflow version, I did tuning it and add a dynamic tuner in the model.
