'qemu-img info' with output format 'json' returns the size and used

integers, but the regex match converts them to strings.
As we know they only contain digits, we can simply cast them back to
integers
after the regex.
The API requires them to be integers.
Any reason for not doing it in the API call itself? That would cover all
plugins and future changes.
The main reason is that we call volume_size_info (which forwards to
file_size_info in most cases) and file_size_info in other parts of our
code as well. Wouldn't it be more consistent for `size` and `used` to be
integers in every context, rather than just in that specific API call?
It doesn't hurt to do it, but it's not persistent, because Perl has no
real types. If it's used as a string some time later (e.g. printed),
it'll be a "string" again.
When converting to JSON, the result depends on how the variable was last
used, so IMHO it should happen as close to that point as possible.
Yes, that's what lead to this situation in the first place.
I'll send a v2 then with both this change and the cast in the API call.
