   currently enabled null support is a table-level configuration. we need to 
create column-level null support to indicate whether a column is nullable.
   
   This:
   1. enables calcite to generate more efficient plan when column is 
non-nullable.
   2. provide runtime better boxing/unboxing optimization, currently everything 
need to handle in generic fashion
