Major Features and Improvements

• Support Tensorflow Estimator for large scale data and distributed training.
  • example: Estimator with TFRecord
  • example: Estimator with Pandas DataFrame
  • Estimator Models API
• Support different initializers for different embedding weights by settting embeddings_initializer of SparseFeat
• Support using pretrained weights to initialize embedding weights and frozen embedding weights. example
• Add new model FwFM
