* IAM User Cloudformation Enhancements: update, delete, getatt.
* AWS::IAM::Policy Support
* Added unit tests for AWS:IAM:Policy for roles and groups. Fixed bug related to groups.
* AWS:IAM:AccessKey CloudFormation support.
* Refactor of CloudFormation parsing.py methods to simplify and standardize how they call to the models. Adjusted some models accordingly.
* Further model CloudFormation support changes to align with revised CloudFormation logic. Mostly avoidance of getting resoure name from properties.
* Support for Kinesis Stream RetentionPeriodHours param.
* Kinesis Stream Cloudformation Tag Support.
* Added omitted 'region' param to boto3.client() calls in new tests.

* Support for CloudFormation stack resource deletion via backend resource method
delete_from_cloudformation_json() via parse_and_delete_resource().
* Correction to the inappropriate inclusion of EndingSequenceNumber in open shards.
This attribute should only appear in closed shards. This regretfully prevents
confirmation of consistent record counts after split/merge in unit tests.
* Added parameters/decorator to CloudFormationModel method declarations to calm-down Pycharm.
