iotests.py: Add QemuStorageDaemon class

This is a rather simple class that allows creating a QSD instance
running in the background and stopping it when no longer needed.

The __del__ handler is a safety net for when something goes so wrong in
a test that e.g. the tearDown() method is not called (e.g. setUp()
launches the QSD, but then launching a VM fails).  We do not want the
QSD to continue running after the test has failed, so __del__() will
take care to kill it.
