Deal with all AWS Route53 (DNS) related issues in order to run an Enterprise Knowledge Graph (EKG) (or a semantic Digital Twin (DT), in AWS.
The main production DNS zone (called main-domain in the code) would be something
like <your-EKG>.<your-org> (e.g. ekg.ekgf.org or digital-twin.ekgf.org).
For each other environment, not being prod, such as dev, staging, test etc., a subdomain is created such
as dev.ekg.ekgf.org or staging.digital-twin.ekgf.org.
