Investigate replacing Routes with Ingress

[jpkrohling]

Looking at some OpenShift 4.x docs, I got the impression that regular Kubernetes Ingress resources are recognized by OpenShift and used as base for new routes. If that confirms to be true, we can just get rid of the Route resource in the Jaeger Operator, keeping Ingress for both OpenShift and Kubernetes.

Would need to be sure the upgrade mechanism handled it, so routes were then converted into equivalent ingresses.

This would probably also help with the issue that on Openshift, routes ignore the hostnames set for Ingress controllers per https://github.com/jaegertracing/jaeger-operator/issues/135.

Could you please create a new issue explaining your issue?
