> * Show Bucketing version for ReduceSinkOp in explain extended plan - this helps identify
what hashing algorithm is being used by by ReduceSinkOp.
> * move the actually selected version to the "conf" so that it doesn't get lost
> * replace trait related logic with a separate optimizer rule
> * do version selection based on a group of operator - this is more reliable
> * skip bucketingversion selection for tables with 1 buckets
> * prefer to use version 2 if possible
> * fix operator creations which didn't set a new conf
