v3 API response changes

In v3, HTTP codes are mapped to the response type.

v2	v3
The HTTP code for each response is `200`.	HTTP codes are mapped to the response type. - `200`/`201`: Successful response - `4XX`: Client side unauthorized, forbidden, or bad request errors - `5XX`: Server side errors
The API response structure includes the `response_status` and `response_message` fields, and the `response_data` object. For list operations, `response_data` is an array of objects.	`200`/`201`: The response directly presents all the response fields and is not in a `response_data` object. For list operations, the response is an array of objects.
For an error response, the `response_data` object includes the `error_code` and `error_message` fields.	`4XX`/`5XX`: The response is an array of objects. Each object includes the `timestamp`, `code`, `severity`, `category`, and `message` fields. See the 4XX and 5XX responses for any endpoint in the API reference for more information.
