HTTPRouteFilter should use union type validation when it is available

[robscott]

What would you like to be added: A +union tag on the HTTPRouteFilter type would be fitting, unfortunately this will not do anything right now.

Why this is needed: This will provide better validation for filter types and would represent one less thing we'd need to cover with webhook validation.

As I understand it, this is currently blocked by https://github.com/kubernetes/enhancements/issues/1027 (and subsequent controller-tools support). That means this will likely not be possible anytime in the next 6 months.
