🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secret safely. Learn here the best practices.
3. Revoke and rotate this secret.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.

Hey @amhudson i think lets do a session on this in the next Boomerang community call. I think we could also be changing this in the Parameter Manager

I've rewritten part of this in https://github.com/boomerang-io/flow.service.engine/blob/main/src/main/java/io/boomerang/service/ParameterManagerImpl.java

It still uses the paramLayers and builds them up. But i think overall we could solve this similar to how you have it.
