Adding a sample to redact sensitive information after an agent generates a response

[Git-Noob123]

Why are these changes needed?

There's a need for a way to redact sensitive data that is stored as env variables. Currently the only way to do this is to use transform_messages which ONLY redacts before an agent generates a response. However, if a user asks an agent to run a script that retrieves env data, it's still going to be revealed. So a way to hide sensitive data after a response is generated is needed. The sample here shows how can we do it using hooks

@Git-Noob123 thank you for the notebook!

I like this notebook since it's a good example to show how process_message_before_send (hooks in general) works.

If we hook TransformMessages onto process_message_before_send it makes debugging these agents much more difficult, since you don't know the ground truth (as it gets modified before being stored in the context history). And as you may already know, it's already difficult to debug vanilla LLMs without any modifications.

In the intro, we should maybe explain the differences between each hookable method, and why you picked the process_message_before_send

@WaelKarkoub Thanks for the comments! I have resolved all of them besides the regex one. I added a section at the beginning of the notebook to describe what's hooks in Autogen as well. Please review it and feel free to put in more comments & thoughts.

For debugging with the postprocess hook, I think we should add another section in the notebook to warn readers about how difficult it can be to debug with redacted message, and users can potentially add logging before redaction. On the other hand hiding sensitive information is more of a security concern, as you dont want users to see your secrets. Please let me know what you think

Hi @Git-Noob123 - I approved yesterday but the base branch moved on again - I can't update yours since it's a fork. If you bring it up to date we can merge.
