Add YANG modules used by SDN-R apps

Applications of wireless artifacts supports a couple of YANG modules
from various SDOs. Most of them might be "learnt" by ODL (CCSDK) when
connecting the frist time to a NetConf Server during handshake,
(HELLO-MESSAGE). APIs based on YANG modules might be used south-
bound and northbound.
