    bug work around of Java MOXy bug of 475475

    On port creation with dns_name: None, null pointer exception occurs
    in opendaylight. This is due to the following bug
    https://bugs.eclipse.org/bugs/show_bug.cgi?id=475475
    EClipsLink MOXy is used as json parser and it wrongly parses json
    and stores wrongly null. In order to work around it, networking-odl
    shouldn't send unmapped keys whose value is null.
