Set veth_mtu default to 9000

Unfortunately we may have to continue to support veth connections
in the OVS agent for QoS use-cases. Related discussion:
https://bugs.launchpad.net/bugs/1550501

For the particular veth connections that reference the 'veth_mtu'
setting, they are constructed long before we know the MTUs of the
networks that will be going over them. So this patch changes their
default to be 9000 to try to ensure they won't be silently dropping
frames in jumbo MTU deployments.
