Bug 1321289

Description of problem:
Create two routers with host-network which will serve for the routes in all the namespaces on a multi-tenant env, create route and update the route with user. Check the route info from client side. 

Not all the routers show the updated route.


Version-Release number of selected component (if applicable):
openshift v3.2.0.7
kubernetes v1.2.0-36-g4a3f9c5
haproxy router ef080f3084e8

How reproducible:
always

Steps to Reproduce:
1. Setup multi-node env
2. Create two routers with host-network
# oadm router --replicas=1 --service-account=router router1 --host-network=true
# oadm router --replicas=1 --service-account=router router2 --host-network=true
3. Create a route by any user
# oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/unsecure/list_for_unsecure.json
4. Check the route info via client
5. Update the route
eg, update www.example.com to www1.example.com
6. Check the route info via client again


Actual results:
4.

Expected results:
The route info on all the routers should be reported back to client side.


Additional info:
Check the haproxy configs on the router pod which does not report back. Can find the route had been updated.
Try to visit the new route via both routers, and both work.
