Cifar keras refactor

- kears_cifar_main returns dict of stats after run.

For tf2 this will only be available in `compat.v1`.

1. `tf.contrib.data.batch_and_drop_remainder()` has been deprecated for a while now.
2. `Dataset.make_one_shot_iterator()` is no longer necessary in input functions, and avoiding it lead to better performance on TPUs. (It will also be removed in TF 2.0.)

input_url doesn't get correct url string in Windows. The os.path.join() function add "\\" to the path, and it resulted invalid URL for the data file.
