[Spark-8690][SQL] Add a setting to disable SparkSQL parquet schema merge by
using datasource API
The detail problem story is in
https://issues.apache.org/jira/browse/SPARK-8690
General speaking, I add a config spark.sql.parquet.mergeSchema to achieve
the sqlContext.load("parquet" , Map( "path" -> "..." , "mergeSchema" ->
"false" ))
It will become a simple flag and without any side affect.
