Toshio Kuratomi cc343a4376 Port ansible doc for plugins to use DOCUMENTATION variables
* Using docstrings conflicts with the standard use of docstrings
* PYTHON_OPTIMIZE=2 will omit docstrings.  Using docstrings makes future
  changes to the plugin and module code subject to the requirement that we
  ensure it won't be run with optimization.
