    gio-tool: -d option to delete attribute
    
    gio tool has support for deleting attributes of the file. To delete attribute user
    should specify type '--type="unset"'. This is not mentioned in help and therefore not
    intuitive. By adding '-d' option, we make this process more obvious.
    
    closes #2588
