[libvirt] [PATCH 3/3] qemu: backup: Implement support for backup disk bitmap name configuration

Use the user-configured name of the bitmap when merging the appropriate bitmaps for an incremental backup so that the user can see it as configured. Additionally expose the default bitmap name if nothing is configured.
