Add special handling for BGP RouteDistinguisher
Add special case code in MdsalHelper for BGP RouteDistinguisher class -
a custom class implemented by OpenDaylight that does NOT follow
the pattern of data object classes generated from Yang models
by Yangtools
Note: this depends on the following ccsdk/parent change to add
OpenDaylight BGP dependencies to the dependencyManagement
section of our parent poms:
