> Currently, for most operators / functions, Drill would always claim the return types
being nullable-any. 
> However, in many cases (such as Hive, View, etc.), the types of input columns are known.
So, along with resolving to the correct operators / functions, we can infer the output types
at planning. 
> Having this mechanism can help speed up many applications, especially where schemas alone
are sufficient (e.g., Limit-0).
