Added preallocation option for raw NVMe disk images.
It matches qemu-img option for raw images.
By default raw images are created with "off" option,
resulting in increased size of the disk image as it is used.
Using "falloc" option preallocates the full size of the disk,
but does not write zeroes to it, compared to "full" option.
This will make sure that in CI, a device used during test
is never exhaused due to lack of host space.
