Migrate from openai==0.28.1 to openai==1.2.4

[johny-b]

I've tested a few evals and they seem to work.

Things I did:

• run openai migrate
• add "import openai" where it was necessary and removed by the migration script
• change ["id"] to .id in registry.py
• remove "api_base" and "api_key" arguments where they are no longer accepted
• add model_dump() in both get_completion functions

NOTE: THIS IS NOT READY YET.

• I don't know why we had "api_base" and "api_key" where I removed them - perhaps they should be now passed somewhere else?
• some unit tests fail, seems related to the previous point
• things could be prettier (e.g. we use client object in openai_completion_create_retrying but not in openai_chat_completion_create_retrying)
• we get a stdout log for every API request which is not convenient
• it seems that now when we exceed the context window, we're repeating the request (issue]

Closing as we've resolved this in #1420.

Thanks for starting this work here and encouraging us to finish this upgrade!
