Separate Staging and Prod Terraform instances

[nour-massri]

Currently we have one Terraform state that handles both staging and prod environments, however from our recent endeavors with deploying terraform updates to staging we experience some extremely sus behavior where we saw some of the staging changes in prod causing it to break. The fix was to do another prod backend and frontend release.
However, we need more investigation to know why this behavior occurred in the first but more importantly we need complete separation of staging and prod environments.

A potential approach to do this without risking breaking any prod is to create a new tf state for staging and delete staging components from the original tf state.
