Comment 2 for bug 1262785

By changing Q_PLUGIN=openvswitch from ml2 to openvswitch, two charactistic change in this bug, 1) when do not need https://review.openstack.org/#/c/61663/ do get throught the migration issues assocatied with using ml2, and, 2) we no longer see the tag: 4095 assocaited with an internal VLAN. Using the Q_PLUGIN=openvswitch all internal ports appear as they should with "tag: 1", though the floating_ips is still failing, but volumes and neutron-adv-test PASS.
