imageutils: Report format specific details when using JSON output format
The data held within this section is particularly useful when dealing
with encrypted LUKSv1, as shown below:
$ qemu-img info --output=json rbd:volumes/volume
{

}
],

},
}
Unfortunately the only documentation for this is in the QEMU codebase at
present, for example for LUKSv1:
