Description of problem:
create pod, service and route, make sure the route can be reached via F5 server. Then delete the service, but the route still can be reached.
Checked the pools and polices on F5, found that the service was not removed from the pools after deleting service.

Version-Release number of selected component (if applicable):
openshift v3.4.0.26+f7e109e
kubernetes v1.4.0+776c994
etcd 3.1.0-rc.0


How reproducible:
always

Steps to Reproduce:
1. oadm router f5router...
2. Create pod, service and route.
   #oc create -f  https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/list_for_pods.json
   #oc expose svc service-unsecure 
3. curl the route.
   #curl --resolve $route:80:$f5-ip http://$route
4. delete the service
   #oc delete sve servie-unsecure
5. repeat step 3

Actual results:
the route can be reached in both step3 and step5.

Expected results:
the route should be unreachable in step5 since the service and endpoint has been deleted.

Additional info:
after deleting the service, no endpoints for the route
