Re: [libvirt] [PATCHv2 48/62] qemu: monitor: Retrieve blockstats also by qdev and node-names

For use with -blockdev we need to be able to retrieve the stats by 'qdev' for the frontend device stats since 'device' will be empty. Note that for non-blockdev case qdev and 'device' with 'drive-' skipped would be the same. Additionally so that we can report the highest written offset we need to also be able to access them by node-name for backing chain purposes. In cases when 'device' is empty it does not make sense to gather them. Allow arranging the stats simultaneously in all the above dimensions.
