Zoltan Borok-Nagy 2ee914d5b3 IMPALA-5903: Inconsistent specification of result set and result set metadata ...

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.
