Support for nullable/x-nullable

[kedashoe]

Hello, just getting started with swagger and came across ReDoc. Really great, got it working pretty quick despite having no idea what I'm doing :p

I'd like to use nullable for a couple properties in an object definition. I came across this issue and it looks like the OpenAPI folks are indeed going to support it in the future.

Can ReDoc add support to the ui for either/both of x-nullable/nullable? Thanks!

@kedashoe thanks for the feature request.
This is probably required for many real-life APIs. So yes, this will be supported by ReDoc.
