netperf_node test case improvement.

JIRA: YARDSTICK-423

In the netperf test testcase, input and output parameters are stipulated.
in this submit, add parameters as a output, you could write the output parameters at yaml file.
and the second is if there is a netperf software at target machine,
this machine won't install this software again.
