[OpenAI] Investigate the error message POJO that works for both AOAI and OAI

[mssfang]

For POJO Investigation, we can't add customized exception to below Maps exception hierarchy. Because the exception structure could change, we only know the exception should have error code and error message. Other values such as value and inner error which is optional. If service changes the exception type to return, it breaks our SDK exception type. Thus, we SHOULD not add the customized exception type in SDK.

try {
    ChatCompletions chatCompletions = client.getChatCompletions(deploymentOrModelId, new ChatCompletionsOptions(chatMessages));
    System.out.println(chatCompletions.getId());
    System.out.println(chatCompletions.getCreatedAt());
} catch (HttpResponseException ex) {
    HashMap<String, Object> exValue = (HashMap) ex.getValue();
    HashMap<String, Object> errorMap = (HashMap) exValue.get("error");
    HashMap<String, Object> innerErrorMap =(HashMap) errorMap.get("innererror");

    ContentFilterResultDetailsForPrompt contentFilterResult1 =
            BinaryData
                    .fromObject(innerErrorMap.get("content_filter_result"))
                    .toObject(ContentFilterResultDetailsForPrompt.class);

}

(1) and (2) Azure OpenAI service team should align the exception message. NO ACTION in SDK side.
