[Feature Request]: Agent framework to integrate third party features.

[AgentGenie]

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

One kind of issues we have is that the third party usually create stand alone agent and we need to integrate those if we would like to support the those.
e.g. LlamaindexAgent
FalkorDB Agent https://github.com/FalkorDB/GraphRAG-SDK/tree/main/graphrag_sdk/agents

Instead of integration of third party ourself, we could promote AutoGen by providing an agent library/framework for the third party to easily create AutoGen agent.

Describe the solution you'd like

An agent library/framework that third parties could easily use to create an AG2 agent
