Fix hard coded AWS Partition

[AbdulR3hman]

Issue #, if available:
AWS Partition was hard-coded for many of the resources in the cloudformation. I have made the changes to ensure that we programmatically substitute the correct partition.

I have tested this by both deploying to commercial and non-commercial regions.
