* New module CloudTuner - Implementation of a library for hyperparameter
tuning that is built into the KerasTuner and creates a seamless integration
with
[Cloud AI Platform Optimizer](https://cloud.google.com/ai-platform/optimizer/docs/overview)
as a backend to get suggestions of hyperparameters and run trials.
* New application Monitoring - TensorFlow extension that exports its metrics
to Stackdriver backend, allowing users to monitor the training and inference
jobs in real time.
* New experimental project cloud_fit - an experimental module that enables
training keras models on
[Cloud AI Platform Training](https://cloud.google.com/ai-platform/training/docs/overview)
by serializing the model, and datasets for remote execution.
* Small bug fixes.
