[SPARK-13928] Move org.apache.spark.Logging into org.apache.spark.internal.Logging

## What changes were proposed in this pull request?

Logging was made private in Spark 2.0. If we move it, then users would be able to create a Logging trait themselves to avoid changing their own code.

## How was this patch tested?

existing tests.
