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.
