* 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.
* only complain about ini deprecation if value is set
* set plugin config for stdout and other types
* updated plugin docs, moved several plugins to new config
* finished ssh docs
* fixed some issues seen in plugins while modifying docs
* placeholder for 'required'
* callbacks must use _plugin_options as _options already in use
renamed plugins to contrib (they are not really plugins)
rewrote README.md to reflect new usage
added new dir to setup.py so it gets copied with installation, in views
of making using inventory scripts easier in teh future
