Clone config parse yaml clone container

These patches create a tool which clones container from yaml file which is written configuration information.
In addition, they move ```utility.py``` and ```definevalue.py``` in ```creator/``` directory to ```common``` directory.

I fix the variable name to 'yaml_data' at 297f80e revision.
