Fixed Failures in CloudFormation Provisioning of S3 Buckets When Stack has Long Name... (#3169)

Browse source 
* Fixed defect with CloudFormation provisioning of S3 buckets occuring when stack has a long name, resulting in the default S3 bucket name's length exceeding its 63 char limit.

* PR 3169 July 23, 2020 2:57a ET comment: added additional asserts to assure provisioned bucket's name complies.  Fixed bug in my earlier change that could produce default bucket names with illegal upper-case characters in it.
