[SPARK-15991] SparkContext.hadoopConfiguration should be always the base of
hadoop conf created by SessionState
## What changes were proposed in this pull request?
Before this patch, after a SparkSession has been created, hadoop conf set
directly to SparkContext.hadoopConfiguration will not affect the hadoop conf
created by SessionState. This patch makes the change to always use
SparkContext.hadoopConfiguration as the base.
This patch also changes the behavior of hive-site.xml support added in
https://github.com/apache/spark/pull/12689/. With this patch, we will load
hive-site.xml to SparkContext.hadoopConfiguration.
## How was this patch tested?
New test in SparkSessionBuilderSuite.
