verified with cluster launched by cluster-bot (launch openshift/router#247) and passed

$ oc get clusterversion
NAME      VERSION                                           AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.6.0-0.ci.test-2021-01-26-012650-ci-ln-27r6lp2   True        False         64m     Cluster version is 4.6.0-0.ci.test-2021-01-26-012650-ci-ln-27r6lp2

1. create route shards with two more custom ingresscontrollers, one is using namespace label and one is using route label.

spec:
  namespaceSelector:
    matchLabels:
      namespace: router-test

spec:
  routeSelector:
    matchLabels:
      route: router-test

2. create two projects, pods, services and routes, ns1 is labelled as "namespace=router-test", route2 in ns2 is labelled as route=router-test 

3. scale up/down the pods in ns2, no reload in the router pod with namespace label.

4. scale up/down the pods in ns1, no reload in the router pod with route label.
