[SAM] Review templates and find points to replace with Mappings data

[binchoo]

To-be: The overall goal is to find an elegant way to provide test/prod environments to the PaimonGanyu's architecture.

• Have two different AWS accounts per test/prod environment.
• The Mappings area isn't currently in use. Review and find some points that mapping data can replace.
• Consider using Lambda alias to provide test/prod environments for the workflows in the paimonganyu stack. Two siloed accounts will separate the environments.

Change of Impact

New DNS Hosted Zone

• I acquired a new domain name for PaimonGanyu: paimon.studio. Its name was considered for future business.

New AWS Account for Test Environment

• PaimonGanyu is manged by two AWS accounts per environment(test/prod).
  • Test environment manger - paimonganyu-test:pgtest
  • Production environment manager - jbinchoo-aws:pgprod

Third-Level Domain for Test Environment in the New Account

• The new account paimonganyu-test created a Route 53 Hosted Zone - test.paimon.studio. It manages DNS records for instances in the test environment.
• To resolve (*.)test.paimon.studio domain names, jbinchoo-aws created an NS record within its paimon.studio hosted zone, which will propagate DNS requests to the name servers that paimonganyu-test account has.
