Subject: [PATCH] qemustatusxml2xmldata: Add 'throttlefilter' tests
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

* Add tests for throttlefilter nodename parse and format for statusxml
(disk/privateData/nodenames/nodename with type='throttle-filter')
* Add iotune limited disk tests to make sure iotune refactory works

Signed-off-by: Chun Feng Wu <danielwuwy@163.com>

* Isolate status xml test
