add promptflow example

[lordlinus]

Why are these changes needed?

This pull request introduces an example of how to incorporate Autogen within a workflow using PromptFlow. PromptFlow enables the creation, debugging, sharing, and iteration of executable flows, which can then be deployed as API endpoints. Additionally, it provides capabilities for evaluating and monitoring the flow to meet the requirements of enterprise environments.

Thanks for the PR! A few things:

1. Can you add some illustrations of what is PromptFlow and how this application integrates PromptFlow with AutoGen. Right now the README dives directly into "Chat flow" but many users do not know what this means.
2. Can you add a blurb to the Ecosystem page for PromptFlow? You can find existing examples in website/docs/ecosystem.

Great work! Would benefit from an explanation of the usage and role of Redis as well as alternatives to capture intermediate msgs during agent interactions.

@lordlinus are you available on Autogen's discord? I would like to understand your code better by hopping on a call if possible. I'm facing some errors executing your code on my side. Maybe it's just some environment variables not being set or something trivial.

Error handling and Optional fields if any in YAML and JSON Schema

great start to see more of these shared :

• promptflow is great
• semantic kernel is great
• kernel memory is great

the documentation is 👌🏻very well done

[krishnashed]

@lordlinus I see a nice to have feature which can be developed for easy installation and setup of Promptflow.

pip install pyautogen[promptflow]

This can be replicated to other integrations mentioned in as well #140

But we can take this up later too, I'm just suggesting.
