feat: collections/docs for modelfiles with models

[racso-dev]

Is your feature request related to a problem? Please describe.
It's frustrating having to mention documents manually every time.

Describe the solution you'd like
It would be nice to have a RAG integration inside the Modelfiles definition.
OpenAI and their GPTs allow users to activate RAG and upload documents upon creation of a new GPT.
It would be really amazing to have such a feature ;)

yes, looking at GenAI stack from docker,neo4j.

I am looking for a way to integrate a neo4j knowledge graph which has structured data and RAG pdf chunk data.

[racso-dev]

Any plans on that feature?

[MarlNox]

What's the approach? I'm also very interested in this feature. If there's a roadmap, id be glad to help realize it.
