be extracted from the modules. This gives a way to verify the API that the module provides as well as the version of that API. The hope is that this will make it possible for MaxScale to detect out of date plugins and either adapt to use them or reject loading them. Also added the ability to set a release state on a per module basis. This allows for production ready and non-production ready plugins to be identified.
