Add functionality to run agents as a service

[psschwei]

If I want to run a bee agent as a service, I would like to be able to do that.

There's a variety of ways that could be done:

• add a function to the agent class

agent = BeeAgent()
agent.serve()

• via a decorator to make the agent servable

@serve
def my_agent():
   ...

• as a standalone capability, a la Ray Serve or Knative Functions

I like this a lot since it means agents in a flow could be executing in different hives :)

I've been playing around in this space a lot, so will assign to myself. Happy for others to help as well
