1, setting mtu for phy nic
   a, charm-helpers has the common method to set mtu for phy nic
   b, both quantum-gateway and nova-compute need to set mtu for phy nic
2, setting mtu for veth devices by adding 'network-device-mtu' parameter into /etc/neutron/neutron.conf
   a, neutron-api config parameter 'network-device-mtu'
   b, quantum-gateway and neutron-openvswitch reads the parameter 'network-device-mtu' from the relation, then write the template /etc/neutron/neturon.conf, so this story only supports ovs plugin as well at this stage.
