[SPARK-4528][SQL] add comment support for Spark SQL CLI
The relative JIRA:
https://issues.apache.org/jira/browse/SPARK-4528?filter=-2
While using *spark-sql*, found it does not support comment while write sqls.
**Comment support** is widely using in many projects, it is a necessary to
add this feature.
Added one function *filterComment()* in the source
org.apache.spark.sql.hive.thriftserver.SparkSQLCLIDriver.scala.
##### three comment styles supported:
1. From a '#' character to the end of the line.
2. From a '--' sequence to the end of the line
3. From a /* sequence to the following */ sequence, as in the C programming
language.
This syntax allows a comment to extend over multiple lines because the
beginning and closing sequences need not be on the same line.
