Summary: Remove Shark-related docs and visibility for 2.x

URL: https://issues.apache.org/jira/browse/SPARK-13942
Project: Spark
Issue Type: Task
Components: Documentation, Spark Core
Reporter: Dongjoon Hyun
Priority: Minor
`Shark` was merged into `Spark SQL` since [July
2014|https://databricks.com/blog/2014/07/01/shark-spark-sql-hive-on-spark-and-the-future-of-sql-on-spark.html].
The followings seem to be the only legacy.

*SparkEnv visibility and comments*

- * NOTE: This is not intended for external use. This is exposed for Shark and
may be made private

For Spark 2.x, we had better clean up those docs and comments in any way.
However, the visibility of `SparkEnv` class might be controversial.
At the first attempt, this issue proposes to change both stuff according to the
note(`This is exposed for Shark`). During review process, the change on
visibility might be removed.
