Public bug reported:

This test is intermittently failing [1] for dvr+ha gate job.
DVR+HA gate job will be running in a 3 node devstack setup. Two nodes will be running l3 agent in "dvr_snat" node and another in "dvr" mode. 
In this job, for dvr routers, we call add_router_interface[2] and then add this router to l3 agent [3].
1) add_router_interface will by default add router to one of the dvr_snat agents, for example agent1
2) when the test is again trying to add explicitly the router to agent,
   a) if adding to same agent i.e agent1, then neutron skips this request [4], hence test passes 
   b) if adding to other agent i.e agent2, then neutron raises exception [5], and test fails 

Till now we have only two nodes(one dvr and another dvr-snat) in gate
for dvr multi node setup. So this test is passing as we are trying to
add to same snat agent(and neuron skips this request). As we are not
really testing any functionality for dvr, we should skip this test for
dvr routers.
