Pull Request Overview

This PR enables dynamic model switching functionality across CodeGen and ChatQnA services. The changes modify how model identifiers are passed through the request pipeline, allowing clients to specify which model to use rather than being hardcoded to default values.

Key changes:

• Updated request handling to pass model parameter with proper fallback to default values
