swift-bench logs stacktracing (when using v2)

[Chmouel Boudjnah]

I am getting this when running swift-bench in 2.0 mode :

stack@devstack:~$ swift-bench -V 2.0 -U admin:admin -K KAKA -A http://localhost:5000/v2.0

That logger = logging.getLogger() and follow settings change the work of root logger, like level or format
public module use its root.module will match these settings and response this, which results in that connectionpool could not find keyword "server"

To fix it, changing logger to module itself, just use logging.getLogger(__name__) is ok

The fix seems to work. To me it would make more sense if swift-bench were part of swiftclient rather than swift. Then you could run it against different swift versions. Is there reason it is not?

    Change logger name to module itself instead of root

    Using root logger will make public module log failed by unknow keyword.
    Just change the logger name to module itself could dismiss this impact.
    And disable logger.propagate could prevent double outputing.
