## What changes were proposed in this pull request?

The name of Spark Thrift JDBC/ODBC Server in web UI reflects the name of the class, i.e. org.apache.spark.sql.hive.thrift.HiveThriftServer2. I changed it to Thrift JDBC/ODBC Server (like Spark shell for spark-shell) as recommended by jaceklaskowski. Note the user can still change the name adding `--name "App Name"` parameter to the start script as before

## How was this patch tested?

By running the script with various parameters and checking the web ui
