[SPARK-6048] SparkConf should not translate deprecated configs on set

There are multiple issues with translating on set outlined in the JIRA.

This PR reverts the translation logic added to `SparkConf`. In the future, after the 1.3.0 release we will figure out a way to reorganize the internal structure more elegantly. For now, let's preserve the existing semantics of `SparkConf` since it's a public interface. Unfortunately this means duplicating some code for now, but this is all internal and we can always clean it up later.
