Add region to S3 origin host names for CloudFront

[JimTharioAmazon]

Describe the bug
We are using global domain names for S3 origins in CloudFront which can take time to propagate
This is true for buckets hosted outside of us-east-1

To Reproduce
Steps to reproduce the behavior:

1. install MSAM into any region not us-east-1
2. open MSAM browser application
3. browser will response will a redirection error for several hours

Expected behavior
Browser application loads and initializes

Additional context
Use bucket names with region included and CloudFront will work as expected:
