commit: Add filter-node-name to block-commit
Management tools need to be able to know about every node in the graph and need a way to address them. Changing the graph structure was okay because libvirt doesn't really manage the node level yet, but future libvirt versions need to deal with both new and old version of qemu. This new option to blockdev-commit allows the client to set a node-name for the automatically inserted filter driver, and at the same time serves as a witness for a future libvirt that this version of qemu does automatically insert a filter driver.
