Add %network%InterfaceDefaultRoute for compatibility

Since https://review.openstack.org/645039, parameter
ExternalInterfaceDefaultRoute is passed to nic config
templates for roles with the default setting for
controller nodes 'default_route_networks: ['External']'
in roles data.

Add the parameter with '' default in tht/net-config-*
templates for compatibility.
