Create instructions on how to change settings to change an env-dev deployment to an env-prod

[brendanbabb]

For users who have deployed terraform in an env-dev deployment and things are working and want to change settings to an env-prod configuration to have more safeguards for accidentally deleting the data store.

Very nice recommendation. Is this something you know how to document, or get started documenting? Maybe a new technical doc here: https://github.com/LouisvilleMetro/WazeCCPProcessor/tree/master/docs Then we can get Slingshot or other Terraform folks to help flush out and verify the details.
