Description of problem: The following tests are failing for us: 1. test_router_create_tenant_distributed_returns_forbidden 2. test_convert_centralized_router 3. test_create_distributed_router The reason is "Unrecognized attribute(s) 'distributed'". This is because our neutron plugin doesn't implement the DVR extension (we are not using the L3 agent and have our own way of distributing the L3 work). We're running the OSP7 certification tool for routers, networks, subnets, ports, and floatingips. Is there a way to disable the dvr related tests?
