Support for RegularExpression path type on HTTPRoute #40
Description
As per https://docs.cloud.google.com/kubernetes-engine/docs/how-to/migrate-ingress-gateway#feature-comparison, there is no support for RegularExpression available on URL rewrites. Could we have the support enabled please?
Gateway API natively support it and relies on implementation specific support https://gateway-api.sigs.k8s.io/reference/spec/#httpurlrewritefilter:~:text=PathPrefix-,Enum%3A%20%5BExact%20PathPrefix%20RegularExpression%5D,-value%20string
