Cleaned up formatting in cli 

I cleaned up all the whitespace and formatting issues in cli but I left in a couple other issues that we should clean up.  a couple of variables that get called assigned but never used.  Is there any reason **not** to clean these up in the future?


cli/cloudlet.py:149:13: F841 local variable 'cloudlt' is assigned to but never used
cli/config.py:34:9: F841 local variable 'wrapper' is assigned to but never used
cli/parameter.py:36:9: F841 local variable 'wrapper' is assigned to but never used
cli/stack.py:219:13: F841 local variable 'y' is assigned to but never used
