json objects should be merged with deep merge

See http://vertx.io/docs/apidocs/io/vertx/core/json/JsonObject.html#mergeIn-io.vertx.core.json.JsonObject-boolean- With parameter deep set to *true*, we have a real merge of the values. So it is possible to add different stores with e.g. json files and merge all the contents together.
