Set VLAN MTU size when creating the vlan interface.
When empty (the default) nova will not set any MTU parameters. You can
specify a number as in --network_device_mtu=9000 to enable jumbo frames,
for example.
Updates:
* change flag name
* set mtu in ovs driver
* empty string means don't fiddle with the interface mtu
* Use None instead of '' for flag default
