[PATCH v2] Complete python module arguments

[Ronan Pigott <ronan@xxxxxx>]

Python modules can behave like commands in their own right. This allows
modules to define _python_module-* functions that are used to complete
module arguments. Also gets the ball rolling by defining completions for
venv, http.server, and json.tool.
