Add KinesisDataset support for tensorflow Dataset (#19712)

* Add KinesisDataset support for tensorflow Dataset

This fix is an attempt to add Kinesis support
for tensorflow's Dataset. Kinesis is provided by
AWS as a managed data streaming service. It is
similiar to Apache Kafka, often used in places
where maintaining a independent Kafka cluster on AWS
is not desirable or possible.

This fix adds the Kinesis support for tensorflow Dataset.
Similiar to the Kafka integration in tensorflow,
KinesisDataset outputs tf.string for records.

Test cases have also been added, which could be invoked manually.
