Setting Kinesis Client Library DynamoDB properties fails

[Zambonilli]

When trying to set the Kinesis Client Library dynamoDB properties they are not being correctly passed to the Kinesis Client Library and applied. This issue looks to be caused by the connector's ExecutorBase class not including the dynamoDB parameters in the kinesisClientLibConfiguration's constructor.

I think the fix would be to add the properties for dynamoDB here, https://github.com/awslabs/amazon-kinesis-connectors/blob/master/src/main/java/com/amazonaws/services/kinesis/connectors/KinesisConnectorExecutorBase.java#L48

I can create a PR.
