qos-test: virtio-scsi test node 

Convert tests/virtio-scsi-test in qgraph test node,
virtio-scsi-test. This test consumes a virtio-scsi interface
and checks that its function return the expected values.

Some functions are implemented only for virtio-scsi-pci, so they
don't consume virtio-scsi, but virtio-scsi-pci

Note that this test does not allocate any virtio-scsi structure,
it's all done by the qtest walking graph mechanism
