[Feature Request]: Declarative way of defining a workflow

[baahujain]

Is your feature request related to a problem? Please describe.

I am building a API service which will allow multiple front end apps to create agents and interact with LLMs. Each front end app will have its own unique problem to solve using agentic approach.

Describe the solution you'd like

Can we have a way to define a workflow using json config file. In this json config we should be able to define if it's a group chat or a two-way chat, we should be able to specify the agents involved in the chat and all the configuration of the agents.

Additional context

LlamaIndex just published Agentic document workflow https://www.llamaindex.ai/blog/introducing-agentic-document-workflows
I am think about similar interface for RAG workflow. What is our plan for the workflow feature? @sonichi @qingyun-wu
