Review request for hive.

https://issues.apache.org/jira/browse/HIVE-8600
Repository: hive-git
Description
-------
HIVE-8600 : Add option to log explain output for query
When diagnosing issues, it is useful to have the explain output for the query
already available in log4j log.
This patch adds an option to log the EXPLAIN EXTENDED output after the query
has been semantically analyzed. It re-uses ExplainTask code that prints the
plan.
