[SPARK-23185][SQL] Make the configuration "spark.default.parallelism" can
be changed on each SQL session to decrease empty files
## What changes were proposed in this pull request?
Make the configuration "spark.default.parallelism" can be changed on each
SQL session to decrease empty files.
When execute "insert into ... values ...", many empty files will be
generated.We can change the configuration "spark.default.parallelism" to
decrease the number of empty files.But there are many occasions that we want to
chang the configuration during each session so as not to influence other sql
sentences, like we may use thrift server to excute many sql sentences on a SQL
session.
## How was this patch tested?
unit tests, manual tests
