upgrade:
- As described in the `Mitaka release notes
<http://docs.openstack.org/releasenotes/neutron/mitaka.html>`_
Neutron now correctly calculates for and advertises the MTU to
instances. As such the ``neutron_network_device_mtu`` variable
has been removed and the hard-coded values in the templates for
``advertise_mtu``, ``path_mtu``, and ``segment_mtu`` have been
removed to allow upstream defaults to operate as intended.
