Move the arguments module into cli/ and context_objects into utils

* Note: Python2 is not as intelligent at detecting false import loops as
  Python3.  context_objects.py cannot be added to cli/arguments because it
  would set up an import loop between cli/__init__.py,
  cli/arguments/context_objects.py, and context.py on Python2.
