fields in JSON data sources

------------------------------------------
Summary: Assign NULL value for empty text fields in JSON data sources
Key: DRILL-1554
URL: https://issues.apache.org/jira/browse/DRILL-1554
Project: Apache Drill
Issue Type: Improvement
Reporter: Andries Engelbrecht
Ability for Drill to assign a NULL value to empty text fields in JSON files.
Option to be set at session or system level to implement this assignment.
Avoids errors when casting to different data types without the need to check for empty fields first. Simplifies predicate filters and avoid potential mistakes, if empty text values need to be ignored. Allows for simplification of joins, if casting of data type is required, especially with columns from different data sources.
