PR #4 breaks run.sh in ./uperf

[atheurer]

PR #4 breaks run.sh in the following ways:

• https://github.com/perftool-incubator/crucible-examples/pull/4/files#diff-a4104e7abfb4f1a5817d35d3ffdf6a3387c28e012e97f44db1a3785584319c3e uses a JSON format which is not compatible with the current schema multiplex uses. The format I believe is intended to work with a newly agreed upon schema, but that schema is not yet supported by multiplex. The following format should be used:

{
    "common": [
        {
            "name": "global",
            "params": [
                { "arg": "duration", "vals": ["90"] },
                { "arg": "protocol", "vals": ["tcp"] },
                { "arg": "nthreads", "vals": ["1", "16", "64"] },
                { "arg": "server-ifname", "vals": ["eno1"] }
            ]
        }
    ],
    "sets": [
        [
            {"common": "global"},
            { "arg": "test-type", "vals": ["stream"] },
            { "arg": "wsize", "vals": ["64", "16384"] }
        ],
        [
            {"common": "global"},
            { "arg": "test-type", "vals": ["rr"] },
            { "arg": "wsize", "vals": ["64"] },
            { "arg": "rsize", "vals": ["1024", "16384"] }
        ]
    ]
}

• run.sh no longer uses server_ifname variable, but it is still defined and documented in the run.sh file. Run.sh needs to remove this and at least mention server_ifname needs to be correct in the uperf-multiplex-example.json
