Test-common module update

Update test-common module to be able to deserialize json for yang object
that are not data object (notification, rpcdata).
- change parent to mdsal bing parent to be able to generate classes from
yang files : today converter can only parse json for data object not
notification or rpcdata. A temporary workaroud is to add stub model yang
data object.
- replace getBindingToNormalizedNodeCodec by getBindingDOMCodecServices
to have all the methods of BindingDOMCodecServices.
TODO: clean converter to use methods from BindingDOMCodecServices
and focus converter on parsing/writing json or xml file for data
object, notification or rpcdata.
