This PR enables routing of fully qualified model IDs of the form `provider_id/model_id` even when the models are not registered with the Stack. Here's the situation: assume a remote inference provider which works only when users provide their own API keys via `X-LlamaStack-Provider-Data` header. By definition, we cannot list models and hence update our routing registry. But because we _require_ a provider ID in the models now, we can identify which provider to route to and let that provider decide. Note that we still try to look up our registry since it may have a pre-registered alias. Just that we don't outright fail when we are not able to look it up. Also, updated inference router so that the responses have the _exact_ model that the request had. ## Test Plan Added an integration test Closes #3929 --------- Co-authored-by: ehhuang <ehhuang@users.noreply.github.com>
