Description

Since consistent(disk and memory state) snapshots currently supported only with qcow images, libvirt should:

- allow creation of snapshots with --disk-only flag and throw warning or exception on when it supposed to do consistent state dump with no-args call 'snapshot-create' for example,
- did not try to restore memory state on snapshot-revert, if possible - it`ll short revert time dramatically, for only doing 'rbd rollback' and will not cause 'error: operation failed: Error -22 while loading VM state' in some cases (see attached libvirt log).
