Remove running bee-stack as a requirement to orchestrate multiple agents

[mmurad2]

Goal
A simpler user experience contained in one repo, where the user can set up individual agents and then orchestrate them.

Bottleneck
Revisiting the bee-api and make it simpler for everyday use.

I'm thinking out loud here, but if we could wrap bee-agent-framework-py in fastapi/flask/django/gunicorn/etc so that the main methods could be called using the api spec from bee-api and/or openai api (for example, create agent and run agent), that would get us most of the way there.
