[Python] Add response content to APIError exception

[geometrikal]

Is your feature request related to a problem? Please describe the problem.

The openapi spec we consume (CVAT) does not define all the possible error response codes for some endpoints. This results in the APIError with message The server returned an unexpected status code and no error class is registered etc.

The hassle is I don't know what the server is going to return for these errors, and so updating the schema is done trial and error as errors occur. I had to modify HttpxRequestAdapter so I could see the error response content.

Client library/SDK language

Python

Describe the solution you'd like

Return the response content in APIError exception to help with updating the schema, and also provide the ability to parse unknown errors in the client.

Additional context

No response

Thanks for raising this @geometrikal

This is something that has come up before and is still yet to be implemented. See #5167. Please checkout the issue for more context.

We'll close this for now to track the ask from there.
