We have added logical project before, but to actually finish the prune to reduce the data IO, we need to add related supports in translator and BE. This PR: - add projections on each ExecNode in BE - translate PhysicalProject into projections on PlanNode in FE - do column prune on ScanNode in FE Co-authored-by: HappenLee <happenlee@hotmail.com>
