bindings: Update to support new constraints
Browse files Browse the repository at this point in the history 
This handles mapping from OvsToNative

- min 0, max > 1 && !unlimted to an array
- min 0, max 1 to a pointer
- min 0, max unlimited to a slice

And in NativeToOvs, we convert all cases back in to an
OvsSet
