KYLIN-5878 ReduceExpressionRule does not work for OlapRel
Calcite sometimes gives inappropriate cost in VolcanoPlanner,
let the ReduceExpressionRule run again in post-optimization
so that SegmentPruningRule and FilePruner can work.
ReduceExpressionRule can only work for LogicalProject,
however, OlapProjectRel extends Project. Therefore,
the conversion use these rules in the ReduceExpressionRule don't work.
This pull request will define some rules in the KYLIN
to overwrite the default ones.
