Use max_completion_tokens for OpenAI and Azure OpenAI providers:
The OpenAI API deprecated max_tokens in favor of
max_completion_tokens for chat completions. Newer models
(gpt-4o, o1, o3) reject the old parameter with a 400 error.
AZURE_API_VERSION env var now overrides the default API version:
(falls back to 2024-12-01-preview).
Update tests to test for expected structures
* Remove some 'unnecessary' parameters from OpenAI invocation. The OpenAI
API is getting complicated with the API and SDK changing on OpenAI's end,
but this not getting mapped through to other services which are 'compatible'
with OpenAI.
* Update OpenAI test for this change
* Trying running tests with Python 3.13
* Added Anthropic support for VertexAI
* Update tests to match code
* Fixed private.json usage with Anthropic (I think).
* Fixed test
