This series adds iotest case for IO throttling.
There is a change in qemu-io sub-commands "aio_read" and "aio_write", which
makes the aio requests accounted and the statistics reflected in blockstats.
Note that IO throttling implementation allows overcommiting of requests, so the
actual IO happened in a time unit may be a bit larger than given limits. In the
test case, the stats numbers are compared against 110%, to make room for such
flexibility in order to improve determinism.
