Fix missing allowed network type 'flat' for ODL OVS

The 'flat' network type was missing from the default allowed network
types with OpenDaylight deployments.  This is OVS configuration which
detemrines which tenant network types are supported on a per node basis.
By default, flat should be allowed.
