Vladimir Sementsov-Ogievskiy cff6d3ca43 scripts/simplebench: add bench_prealloc.py 
Benchmark for new preallocate filter.

Example usage:
    ./bench_prealloc.py ../../build/qemu-img \
        ssd-ext4:/path/to/mount/point \
        ssd-xfs:/path2 hdd-ext4:/path3 hdd-xfs:/path4

The benchmark shows performance improvement (or degradation) when use
new preallocate filter with qcow2 image.
