Fastapi: Support for pydantic exclude_none

[ricleal-fugue]

Is your feature request related to a problem

I want to exclude from the output values set to None.
pydantic has support for this: <object>.json(exclude_none=true)

The solution you would like

Similar to the parameter response_model_exclude_unset but to exclude the Nones.

Describe alternatives you've considered

Not setting any None... Lot of boiler plate code.

In the latest versions you can set it in the path operation decorator with response_model_exclude_none=True.

The current latest version is 0.54.1.
