AI openai client configuration

[jamiehodge]

What is the problem this feature would solve?

In order to support proxying requests to openai, allow configuration of client url and possibly make the apiToken optional (as it may be handled by the proxy).

What is the feature you are proposing to solve the problem?

• an additional config var for url, with a fallback to the current value
• making the apiToken and authorisation header optional

What alternatives have you considered?
