    Add support for compressing qcow2 snapshots
    
    Fixes bug 1109923
    
    Adds a new configuration option:
        libvirt_snapshot_compression=False (Default)
    
    When set to True and the snapshot output format is qcow2, we pass
    the -c option into qemu-img, which enables compression. This patch
    also refactors the extract_image function to make construction of
    the whole qemu-img command more dynamic.
