Checking with users if this is something they'd want

Seems like this should be opt-in.

Since this is for key-owners happiness, and we already gate key-owner specific permissions behind allow_user_auth - https://docs.litellm.ai/docs/proxy/ui#step-2-enable-user-auth

We can gate this feature behind that too.
