    tests/blackbox: add test for net ads JSON output
    Implement blackbox tests for
        $ net ads info --json
        $ net ads lookup --json
    that validate
        a) JSON wellformedness (by feeding it into the JSON library
           that ships with Python), and
        b) equality of the set of keys printed to that of the
           non-JSON version.
