On seeing that spelled out, I wonder if the '-vm' is just noise; where
we could use 'query-snapshots' instead of 'query-vm-snapshots'.  Then
again, we already have 'blockdev-snapshot-sync', which is an entirely
different snapshot (just a block device, rather than the entire VM), so
dropping -vm is probably a bad idea.  Anyone else want to chime in on
the bikeshed painting discussion of the best QMP name?
