contour: IngressRoute support for custom request timeout

Describe the solution you’d like I’d like to be able to configure custom request timeouts per IngressRoute.

It seems from docs that you can use annotations on ingresses, but according to this comment

IngressRoutes don’t really use annotations for anything

Docs regarding IngressRoute contain no reference to a requests timeout config parameter.

Environment:

• Kubernetes version: v1.10.3 (EKS)
• Cloud provider or hardware configuration: AWS
