    Because we need to reduce the number of ITCases for improving the built time, I propose
a different test structure: Add a `org.apache.flink.table.runtime.dataset.DataSetAggregateITCase`
that tests grouping sets (not cube or rollup) in Scala Table API. The remaining tests can
be logical unit tests for Java Table API, Scala Table API and SQL API. You can find additional
information how we test here: https://issues.apache.org/jira/browse/FLINK-3656
