- [x] I have searched the existing issues and checked that my issue is not a duplicate.

### The Feature

I would like LiteLLM to provide a distinction between the Management API and the LLM API, via the OpenAPI spec.

This is particularly useful in the Multi-Region with Global Control plane model.

### Motivation, pitch

Context: - The LiteLLM OpenAPI Spec is huge at around 700ish operations. - We run LiteLLM behind Azure API Management

Most of my DEV teams will only need access to the LLM API subset of those operations, so I'd like to be able to expose documentation to them at that level, to reduce their context to something more appropriate.

Additionally, this would make a material difference in how I expose the LLM APIs via APIM, as I can logically separate and control the LLM API and the underlying regional workers without replicating huge sections of the API unnecessarily.

### What part of LiteLLM is this about?
