Augmenter refresh schema mapping

Issue 136

Please pay attention to the change in initialization of the augmenter integration tests. The step Then I clean up the index of the extended kinds <extendedKinds> in the Elastic Search was to delete the index in order to enforce the update of schema mapping in ElasticSearch index.

With this MR, the update of the augmenter configuration will automatically update the schema mapping in ElasticSearch index.
