Bypass OpenAI server overload and HTTP 500 Error

[iQuxLE]

This issue was already handled in this old PR but it had a commit mistake. A new PR will be made to have a cleaner history.

When loading ontologies into CurateGPT the insertion of the data into chromaDB is very often interrupted because of a server overload on the API side.

openai.error.ServiceUnavailableError: The server is overloaded or not ready yet.

Implementing a exponential_backoff_request helped me to bypass this by trying again with an additional small sleep every time it would fail.
Its not a fancy solution but it can get the job done.

Another often occurring problem would be an HTTP 500 error, which could also be caught.
