Review Comment:
   Oh got it, that makes sense, it should be a configurable parameter. To be 
consistent with the rest of HiveServer2Statement, I'm just using the 
QueryTimeout parameter (which is what other FetchResultsRequest uses)
   
   I have some changes in a follow-up PR that will make this change easier to 
do for DatabricksReader, will leave this as a TODO
