tests: qemublock: Add test case for detecting bitmaps as we create snapshots
Add test data gathered from a run of qemu after creating bitmaps and snapshots together in various combinations. The following sequence of commands was used to achieve the configuration: virsh checkpoint-create-as VM --name a virsh snapshot-create-as VM --disk-only virsh snapshot-create-as VM --disk-only virsh checkpoint-create-as VM --name b virsh checkpoint-create-as VM --name c virsh snapshot-create-as VM --disk-only virsh checkpoint-create-as VM --name d virsh snapshot-create-as VM --disk-only virsh checkpoint-create-as VM --name current Note that VM was restarted after these operations to allow renumbering of the bitmaps in a more human-readable way.
