Add multi-regional deployment support

# Summary
Multi-regional deployment support is a key feature of AWS. In order to support our current and future client needs, it's been decided that multi-regional deployment support should be added to the capabilities of BitOps.

The change will need to be made so that it doesn't change the current folder structure only adds to it.
