Service Mesh RC1 uses a targetPort name of "http2" for the istio ingressgateways. We use a hardcoded port name of "http" at https://github.com/openshift-knative/knative-openshift-ingress/blob/a1ba148e9b5c331e769fc06af8615cc6b5c881a0/pkg/controller/resources/route.go#L128

I don't know if we can just switch that to always be "http2" or if we need smarter logic here to detect which to use.

Our generated OpenShift Routes (and thus resolvable domains) will not work w/ Service Mesh RC1 until we update this, which is why I marked as a blocker.
