I'm sending patches for all commands in one patch series because the
savevm command depends on delvm command.
This patch series introduces new design of these commands:
* QMP vm-snapshot-save:
- { 'command': 'vm-snapshot-save',
'data': { 'name': 'str' },
'returns':
Finding snapshot by a name which could also be an id isn't best way
how to do it. There will be rewrite of savevm, loadvm and delvm to
improve the behavior of these commands. The savevm and loadvm will
have their own patch series.
Now bdrv_snapshot_find takes more parameters. The name parameter

QMP command vm-snapshot-delete no takes two parameters name and id. They are
optional, but one of the name or id must be provided. If both are provided they
will match only the snapshot with the same name and id. The command returns
SnapshotInfo only if the snapshot exists, if snapshot doesn't
Later in the patch series we will use this function few times.
