[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.
