qdev: allow setting drive property for realized device
We need an ability to insert filters above top block node, attached to
block device. It can't be achieved with blockdev-reopen command. So, we
want do it with help of qom-set.
Intended usage:
Assume there is a node A that is attached to some guest device.
1. blockdev-add to create a filter node B that has A as its child.
2. qom-set to change the node attached to the guest device’s
BlockBackend from A to B.
