AzureOpenAI features not supported and are hard coded

[neilbhutada]

🐛 Describe the bug

In the documentation and the code base there seems to be a discrepancy. In the documentation, it says to use the following environment variables while using AzureOpenAI services, but the name of the environment variables differs. Secondly, I was looking at the source code and it seems that the api version was hard coded. It would be nice to pull the from yaml config. Thirdly, I couldn't see the embedder for AzureOpenAI in the source code.
Thank you!

I was able to load the version from the YAML config, in the latest version, below an example how it worked.

os.environ["OPENAI_API_VERSION"] = "2024-02-01"
