Bug description:
Enabling the Q_USE_DEBUG_COMMAND=True in devstack localrc uses the set_neutron_debug using namespace fails. This usually shows as :

This situation also cause the neutron Grenade(check-grenade-dsvm-neutron) testing to fail as well, see http://logs.openstack.org/63/61663/2/check/check-grenade-dsvm-neutron/5f49167/.
the failing command in floating_ips.sh :
check_command='while ! sudo /usr/local/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ip netns exec qprobe-24ae41f0-4135-4c67-a16f-2eb5f4c313ec ping -w 1 -c 1 10.1.0.4; do sleep 1; done'

After the setup_neutron_debug (https://github.com/openstack-dev/devstack/blob/master/stack.sh#L1110) is called ( ttps://github.com/openstack-dev/devstack/blob/master/lib/neutron#L847), the ovs-vsctl show looks like:

====== which the Port "tap24ae41f0-41" has a tag of 4095 which
should be 1, and the 10.1.0.4 ip address which should be private is
pingable from the host.
