    DRILL-3765: Move partitioning pruning to HepPlanner to avoid the perf…

    …ormance overhead for redundant rule execution.
    
    Add fall back option in planner.
    
    Run the regression/unit with this feature turned on /off.
    
    Please see DRILL-3765 for some performance number.
    
    Regarding the planner options:
    1. planner.enable_join_hep_opt is replaced with planner.enable_hep_opt.  This controls
whether HepPlanner would be used in drill logical planning. If this option is off, it would
fall back to Volcano planner. 
    2. Add new planning option : planner.enable_hep_partition_pruning, which will turn on/off
this feature. If this option is off, it will fall back to the code prior to this patch. 
    
    @amansinha100 , could you please review this patch?
