Snake Case Field Option

Is your feature request related to a problem? Please describe. OpenAPI or JsonSchema may describe key of objects as camelCase. But, attributes of python should be snake_case. The generator should provide a feature that converts filed names CamelCase to sanke_case.

Describe the solution you’d like I would the feature give the generator a command-line option

Maybe I am off base here but I feel like this is doing the opposite of what I am exepcting.

        class Model(BaseModel):
            notification_type: Optional[str] = Field(
                None,
                alias="notificationType",
            )
        self.assertEqual("{\"notification_type\": \"test\"}", Model(notificationType='test').json())

where I was expecting to have

self.assertEqual("{\"notificationType\": \"test\"}", Model(notification_type='test').json())

Since javascript and json is usually camel case, and python is usually snake case.

EDIT: reading through https://github.com/samuelcolvin/pydantic/issues/565 it looks like pydantic is taking the approach that the constructor is taking in the camel case version. It is still odd that the json does not return the public verions.

I implemented this here:

https://github.com/FlorianLudwig/pdk8s/blob/master/pdk8s/gen_k8s.py#L59

By changing the name to camel_case and keeping the old name as alias.
