Preface
Opening early to discuss whether this is a welcome addition, the architectural decisions, documentation implications, and whether expanding this URL config override to other LLMs within the gem's scope makes sense. I'm committed to maintaining the developer experience simplicity of the project's stated mission, so I'm on board with redoing the initial approach to fit in with longer-term priorities (or closing outright!).
Goal
This commit introduces the configuration primitives necessary for semantic caching proxy services for OpenAI requests. Specifically, the option to override the OpenAI root API URL path and the ability to add custom headers to the request payload in the form of a hash. I'm a Fastly employee, and I used our semantic caching product as a test implementation.
In-Progress Disclaimer
This branch does not yet introduce tests and should not be merged until a subsequent commit lands with proper testing.
