K8S Ingress spec missing URL rewrite capability

[m62534]

Missing a way of configuration-as-code/infra-as-code for k8s ingress to perform the following actions (which can be done via gui): https://cloud.google.com/load-balancing/docs/https/setting-up-url-rewrite#modifying_the_url_map

outcome:

1. user navigates to somesite.com/public/ql
2. url map redirects to somesite.com/api/ql/external

The K8s Ingress API is in V1 and does not support providing a rewrite for a path. The Gateway API is meant to replace the Ingress API in Kubernetes and natively supports rewrites. We will look to support this feature in the GKE Gateway implementation.

Please look to the GKE Gateway Docs for more information about the GKE implementation.
