oneOf , discriminator and mapping fields

[david-dotorigin]

openapi-python-client=0.15.2 supports oneOf by trying to parse each option in turn.
It does not seem to support discriminator or mapping so that it knows what to parse.
I think these are all part of the 3.0.3 specification here - https://github.com/OAI/OpenAPI-Specification/releases

Is it that this is missing from openapi-python-client 3.0.3 support and could be submitted as a pull request?
Is it present and working??
Is it not part of 3.0.3?
I'm not sure! :)

My absurd test example is:

...
"content": {
    "application/json": {
        "schema": {
            "type": "object",
            "discriminator": {
                "mapping": {
                    "yes": "#/components/schemas/replyuser",
                    "no": "#/components/schemas/ErrorModel"
                },
                "propertyName": "cheesycheesy"
            },
            "oneOf": [
                {
                    "$ref": "#/components/schemas/replyuser"
                },
                {
                    "$ref": "#/components/schemas/ErrorModel"
                }
            ]
        }
    }
}
...

The string cheesycheesy does not end up anywhere in the generated code which seems conclusive.
The generated code looks just as it would with the discriminator block missing.

Discriminators just aren’t supported yet (see also #830 ). If you’re up for it, I’d love a pull request which adds support 😊
