IMPALA-13637: Add ENABLE_TUPLE_ANALYSIS_IN_AGGREGATE option
IMPALA-13405 adds a new tuple-analysis algorithm in AggregationNode to
lower cardinality estimation when planning multi-column grouping. This
patch add flag ENABLE_TUPLE_ANALYSIS_IN_AGGREGATE that allows user to
enable/disable the algorithm if necessary. Default is True.
Testing:
- Add testAggregationNoTupleAnalysis.
This test is based on TpcdsPlannerTest#testQ19 but with
ENABLE_TUPLE_ANALYSIS_IN_AGGREGATE set to false.
