Bence Romsics 27601f8eea Set trunk parent port as access port in ovs to avoid loop
A non-vlan-transparent trunk parent port (tpt) should only forward
untagged frames. Earlier it was configured to forward anything (trunk
mode in ovs). This patch changes the trunk mode to access mode and
sets the trunk parent's tag explicitly to 0.

The fix of `bug 2048785 <https://bugs.launchpad.net/neutron/+bug/2048785>`_
only fixes newly created trunk parent ports. If the fix of already existing
trunks is needed, then either delete and re-create the affected trunks
or set tpt ports' vlan_mode and tag manually:
``ovs-vsctl set Port tpt-... vlan_mode=access tag=0``
