Why not creating the `PushDownDynamicFilters` one you suggested earlier?
   
   My reasoning for using a parameters was that there's a lot of shared 
implementation both on the optimizer side and ExectionPlan side. E.g. the 
transparent nodes like CoalesceBatchesExec don't really care which phase it is, 
but FilterExec needs to ignore the dynamic phase and SortExec needs to ignore 
the static filter pushdown phase.
