[SPARK-4034]change the scope of guava to compile

After click maven->reimport for spark project in idea, and begin to start "sparksqlclidriver" in idea, we will get a exception:

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/util/concurrent/ThreadFactoryBuilder

This is casued by after maven->reimport was clicked, the scope of guava*.jar in the project spark-hive-thriftserver is changed to provided(rigth click project spark-hive-thriftserver->choose the tab Dependencies, will find each jar's scope in this project ). We can change it to "compile" ,and re-start SparkSQLCLIDriver, the excepiton disappear. But if we re-run maven->reimport, the scope of guava*.jar will return to "provided"
