> Infrastructure changes to support retrieval of query-runtime supplied values, needed
for dynamic min/max (HIVE-15269) and bloomfilter join optimizations.
> - Some concept of available runtime values that can be retrieved for a MapWork/ReduceWork
> - ExprNode/Sarg changes to pass a Conf during initialization - this allows the expression
to retrieve the MapWork at query time (using Utilities.getMapWork(Configuration)) to access
runtime-supplied values.
> - Ability to populate the runtime values in Tez mode via incoming Tez edges
