commit 2b1d413ee90dfe2e9ae41c35ab37253df53fc6cd

Avoid agents adding ports as trunk by default.
Agent OVS interface code adds ports without a vlan tag,
if neutron-openvswitch-agent fails to set the tag, or takes
too long, the port will be a trunk port, receiving
traffic from the external network or any other port
sending traffic on br-int.
Also, those kinds of ports are triggering a code path
on the ovs-vswitchd revalidator thread which can eventually
hog the CPU of the host (that's a bug under investigation [1])
