Fix python module names to comply with script ones

[rwngwn]

in CCT modules invocation we have scheme:
name.package.operation
in script:

• name is name of the dir containing image.yaml
• package is sibling dir of image.yaml
• operation is name of the script

in python:

• name - name of python file
• package - Class name
• operation - method

We should change name of python file to a dir containing image.yaml
