Handle azure_deployment Parameter Issue in GPTAssistantAgent to Maintain Compatibility with OpenAIWrapper

[IANTHEREAL]

Why are these changes needed?

context

The GPTAssistantAgent supports an optional azure_deployment parameter, which, when specified during the initialization of the AzureOpenAI client, leads to a NotFoundError with error code 404 on calling client.beta.assistants.list():

openai.NotFoundError: Error code: 404 - {'error': {'code': '404', 'message': 'Resource not found'}}

Omitting the azure_deployment parameter results in normal operation. This behavior is incompatible with the implementation logic of OpenAIWrapper and implies a potential deficiency in the AzureOpenAI implementation(openai/openai-python#1163).

Notably, GPTAssistantAgent requires the model/azure_deployment to be specified only when calling client.beta.assistants.create.

To circumvent this issue without affecting the existing logic of other agents and before a fix is released for the openai python library, we should locally handle the azure_deployment parameter within GPTAssistantAgent.
