[libvirt] [RFC PATCH 27/30] tests: qemublock: basic qcow2 tests

Add tests for backing chain handling, including a very long chain which is fully specified in the XML and an unterminated chain. The top level disk image would generate the following '-drive': file-qcow2-backing-chain-encryption.xml: -drive file=/var/lib/libvirt/images/a,encrypt.format=luks, encrypt.key-secret=node-b-f-encalias,format=qcow2,if=none,id=drive-dummy -device virtio-blk-pci,scsi=off,drive=drive-dummy,id=dummy file-qcow2-backing-chain-noopts.xml: -drive
