feature request: expose verify param of httpx client

[ccurme]

Confirm this is a feature request for the Python library and not the underlying OpenAI API.

• This is a feature request for the Python library

Describe the feature or improvement you're requesting

httpx allows you to specify SSL contexts when instantiating a client (see httpx docs). Otherwise, httpx will create a new SSL context when creating the client, which is expensive if you are instantiating multiple OpenAI clients.

Exposing verify in openai.(Async)OpenAI would allow you to share the SSL context among clients.

Currently, you'd need to share httpx clients. If you want default params (e.g., base URL) you need to ensure you're consistent with how OpenAI instantiates httpx clients.

Alternatively, OpenAI._client could be made a public attribute.

Hey, are you aware of client.with_options()? that will copy the httpx client over to the new client instance which will improve performance and also let you easily share common options. Would that work for you?
