Make request/response info available in `OpenAIException` when available

[stargazer33]

In case an exception is thrown I want to write in my log file as much as possible, to debug it later: including HTTP response headers!

It is great that .headers() are available in OpenAIServiceException.
Good.

Now make .headers() available in OpenAIInvalidDataException, OpenAIIoException, OpenAIException.

HTTP response headers are extremely important!

Will probably need to be optional/conditional cause some OpenAIException cases do not happen in the course of a request/response (or like at least the response does not exist yet)

Optional is OK
