Gateway support for listening on port range or and port via *?

Hello,

Gateways currently require an explicit listing of ports to expose for incoming connections. Is there any planned support for listening on a large range of ports (ie 5000-9000) or all ports via *?

Use case: we want to be able to run arbitrary development workloads in our istio cluster, and be able to support starting servers on arbitrary ports (or a large range of arbitrary ports). Currently we need to list out each supported port in the ingress gateway.

We can’t as Envoy listener requires knowledge of inbound port in the listener config.
