We'd like to remove the dependence of `llama-stack` on `llama-stack-client`. This is a necessary step. A few small cleanups - Enables `embeddings` now also - Remove ModelRegistryHelper dependency (unused) - Consolidate to auth_credential field via RemoteInferenceProviderConfig - Implement list_models() to fetch from downstream /v1/models ## Test Plan Tested using this script https://gist.github.com/ashwinb/6356463d10f989c0682ab3bff8589581 Output: ``` Listing models from downstream server...
