>          Components: Query Processor, Statistics
>    Affects Versions: 0.14.0

> *FIXES:*
> 1) JOIN rule does not properly propagate the column statistics from its parent
> 2) Multi-way join rule computes the denominator for #rows estimation wrongly
> 3) GROUPBY rule does not account for the data size of aggregate column
> 4) Prefix removal from column names isn't working
> 5) GROUPBY rule looks at missing column statistics for aggregate column from its parent
and assumes PARTIAL column stats state
> *IMPROVEMENTS:*
> 1) Replace "EXPLAIN EXTENDED" with "EXPLAIN" in test cases to make the golden files easy
to comprehend and to reduce verbosity
> 2) Introduce rule for ReduceSink operator which only does renaming of column statistics
as per output row schema
> 3) Add more rows to the test datasets to avoid 0 row scenario in join test cases
> 4) JOIN rule improvement to avoid long overflow
