Azure OpenAI integration support

Here's a patch for the api settings form to allow provider selection. The patch also adds a conditional client based on the service provider.

That said, I'm not working with a typical Azure OpenAI implementation and don't know if this will work for everyone.

If you have any trouble with this patch, share your issues here and maybe I can help.

Modified patch to include correct variable on submit handler

Thanks for posting, I will take a look at this next week. Got backed up on other issues.

@SiliconValet - thanks for the patch! I am getting the below error and I assuming this is because the getModels() function doesn't exist because the model is explicitly declared when creating the client, but most of the sub modules check for that function?

OpenAI\Exceptions\ErrorException: Resource not found in OpenAI\Transporters\HttpTransporter->throwIfJsonError() (line 131 of /var/www/html/vendor/openai-php/client/src/Transporters/HttpTransporter.php).

OpenAI\Transporters\HttpTransporter->requestObject(Object) (Line: 28)
OpenAI\Resources\Models->list() (Line: 86)
Drupal\openai\OpenAIApi->getModels() (Line: 130)

Thanks for your patch

I was thinking if i can use a proxy server forward to OpenAI while I was selecting azure api,
the logical is same, i input base url and apikey, but i failed, the openai said there was not api key.
So i added it in here, everything looks charm.
Hope no other problem appears.

The thing is that, while it can get the Azure API Key, the model array is indeed a problem, as, not only the main configuration, but also most of the submodules expect said model array.

This causes most submodules to show that same error, as they are not able to connect because they are not getting the config info as they expect.

Would it be possible when using azure to set somehow the model array with the fixed model version so other modules can keep working?

I've added the ability to set an explicit model. I missed that in the previous patch.

This patch includes a check for the service provider selected and returns the explicit model provided if you're using Azure OpenAI.

Thanks a lot!

We are going to try it :)
