[SPARK-10659][SQL] Add an option in SQLConf for setting schema nullable in
datasource
JIRA: https://issues.apache.org/jira/browse/SPARK-10659
If not preserve REQUIRED (not nullable) flag in schema is a problem for
users, I think we can add an option (default is enabled) to enable this
behavior or not.
