[SPARK-17686][Core] Support printing out scala and java version with spark-submit --version command ## What changes were proposed in this pull request? In our universal gateway service we need to specify different jars to Spark according to scala version. For now only after launching Spark application can we know which version of Scala it depends on. It makes hard for us to support different Scala + Spark versions to pick the right jars. So here propose to print out Scala version according to Spark version in "spark-submit --version", so that user could leverage this output to make the choice without needing to launching application. ## How was this patch tested? Manually verified in local environment.
