Update Java KinesisIO.Read to support AWS SDK v2

As a contributor to the Java Kinesis IO, I would like a version of KinesisIO that is based on the v2 AWS SDK so that support for enhanced fanout can be added. I would also like this to be a separate work item from adding the enhanced fanout support so that users of KinesisIO can potentially benefit from updating to the v2 AWS SDK while enhanced fanout support is still being worked on.
