Refactor IaC Build Pipeine

[williamputraintan]

The current setup

In each account

1. Lambda that contains the react raw asset push these assets to codebuild via S3
2. Codebuild build react for production with required env-var (based on SSM Parameter)
3. Pushes this prod-asset to S3

The desired refactor:

1. From the build account codepipeline add a react build stage where the env-var is imported from the stage account via AWS RAM
2. Push these react prod assets directly to the stage s3 account.

• These required to setup AWS RAM for each stage account
• Build will solely on the build account

Current UI pipeline as below

Improvement:

• [ ] build custom web hook to let infra pipeline only triggered by deploy cdk code, and code build pipeline only trigger by other code

Thanks for the update! The diagram is super useful and I think we should stick this as part of the deployment docs.
