[PATCH 1/5] Netperf: add netperf debug option

[Jan Tluka]

Netperf test module now takes optional parameter 'nperf_debug'. The value
is number and means verbosity level. E.g.
    debug=0 => netperf ... (no debug)
    debug=1 => netperf -d ...
    debug=2 => netperf -dd ...
    debug=3 => netperf -ddd ... This is the maximum level of verbosity
