Istio operator should redirect http requests to https

During the switch from ingress to route resources it seems we may have missed the opportunity to include https redirection. While I could only find passing documentation in 4.1, the 3.11 documentation has information about the use of "secured routes" with the option:

insecureEdgeTerminationPolicy: redirect

in the TLS spec for the route.

Performing the command:

oc -n openshift-operators get routes

And then going to the resulting hostname will error as follows unless the user manually adds "https":
