[Bug]: Global Overwrite of OpenAI API Key During Text Embedding Execution

[watanabeycr7]

What happened?

When the OpenAIEmbeddingFunction() is executed, the api_key provided as an argument overwrites the openai.api_key that is referenced globally throughout the application. This behavior prevents the application from being able to differentiate between the API key used for embeddings and the API key used for regular chat operations.

Here's a snippet of the affected code:

app.logger.info(f"openai.api_key: {openai.api_key[-4:]}")
app.logger.info(f"ANOHTER_OPENAI_API_KEY: {ANOTHER_OPENAI_API_KEY[-4:]}")

embedding_function = embedding_functions.OpenAIEmbeddingFunction(
    api_key=ANOTHER_OPENAI_API_KEY, model_name=EMBEDDING_MODEL
)

app.logger.info(f"openai.api_key: {openai.api_key[-4:]}")

I've identified the issue and have a possible solution in mind. I'll begin working on a PR to address this.
