Before this commit it was quite random which DDL oprations returned a result set and which didn't. With this commit, every DDL operations return a summary of its execution. They declare their result set schema in Frontend.java, and provide the summary in CalatogOpExecutor.java. Updated the tests according to the new behavior.
