Add OpenAI Function Agents & logging capabilities using aimstack

[srmsoumya]

• Add support for open-ai function agents that better handle parameter passing to tools
• Log experiments using aimstack - easy to compare runs by different agents
• Handle exceptions gracefully

@sunu aimstack stores the log in the root of cwd as .aim/.

We can check the logs in a dashboard by aim up that runs on port 43800 by default. Should we have this running as well to check logs periodically?

Just some initial thoughts:

• If we're going to run aimstack as a service and monitor multiple experiments, we should see if it supports storing/loading data from something more cloud native - like a GCS bucket for example
• If we are ok with running aimstack coupled to this particular streamlit app only, then I guess we can try to run it as a sidecar that will share a storage volume with the streamlit app. In theory, it should work, but may require some figuring out.

I don't foresee us using aimstack for monitoring other experiments, so we can run this as a one-off for now, we can switch to LangSmith once it is out of public beta.
