Support OpenAI models on Azure

[cab938]

Microsoft hosts various OpenAI models on Azure and one of the benefits of these models is that the contract with Microsoft is different than with OpenAI and thus may include additional data protection clauses making this attractive for businesses who want to use foundational models but do not have a direct relationship with OpenAI. It would be great to add support for these models to roo cline.

Here's a list of the models: https://learn.microsoft.com/en-us/azure/ai-services/openai/concepts/models?tabs=global-standard%2Cstandard-chat-completions

Here is the JS API for these models: https://learn.microsoft.com/en-us/azure/ai-services/openai/supported-languages?tabs=dotnet-secure%2Csecure%2Cpython-secure%2Ccommand&pivots=programming-language-javascript

The key difference is that authentication requires additional tokens for configuration.
