OpenAI responses endpoint compatibility #120
Description
It would be nice to have a parity/compatibility with OpenAI API in Paddler to make migrations and integrations easier.
We need compatibility with OpenAI's responses endpoint: https://platform.openai.com/docs/api-reference/responses/create
What is required is to create a mapper that internally maps request parameters into Paddler parameters, then maps our response back into OpenAI format, similarly to this one: https://github.com/intentee/paddler/blob/ade9d9ada349f424dbe8ec281870eafaabe0c588/src/balancer/compatibility/openai_service/http_route/post_chat_completions.rs
If you want to help, and contribute to Paddler, this is a good place to start.
