Describe the solution you'd like

I would like to be able to use the tools provided by crewAI using my custom deployed models on my infrastructure. I think that as long as the tools can use the OpenAPI standard with OpenAI library, then there is easy integration. The only thing that needs to be added is the capability of not relying on providers and just have the same functionality with the custom models deployment like an instance of any model in vllm for example
