Added new to pull in bb-common specific values and updated a few templates to use the new approach

General MR

Summary

• Added new bb-common related helper to help reduce code redundancy
• Tightened scope of mergeLegacyIstioHardened
• Removed logic used for custom ports for Postgres/Redis and associated tests from Gitlab template

Relevant logs/screenshots

Common is now used only for bb-common related settings as shown below:
