[PYTHON] Should be possibile to remove package name from the generated model names

Description

I generate a python client from an open-api v2 spec that comes from a Golang project.

The generated python module names are prefixed with the source Golang package, for example take model_ + build_version_info.py from the screenshot below.

I believe this is expected because the related definition in the swagger file is "model.BuildVersionInfo". However, this is non-ideal because it makes the python client cluttered! I tried tinkering with --model-name-prefix but it'd just prepend a string and not overrides the existing prefix.

Suggest a fix/enhancement

Instead, I'd like to either remove the model_ prefix, or have sub-packages within the models package. Is this even possible?

Start by reproducing the generated Python client with the linked swagger.json, config.json.template, and the shown swagger-codegen generate command. Trace how the model.BuildVersionInfo definition becomes model_ in the Python models, then determine a supported way to remove or replace that prefix; done means generated model names no longer contain the unwanted package prefix without breaking references.
