Curious if we should update the gateway listeners first before updating the httproute

I'm not sure -- how would you decide which to do?

I could imagine a poor implementation (of the gateway api) that doesn't trigger reconciliation of existing HTTP routes when ReferenceGrants for certain namespaces are create.

Thus I think I'd prefer to create the listener & grant and update the gateway prior to creating an HTTPRoute.

I'm ok if that's done in a followup PR
