Add method to PerfLogger to perform cleanup/final steps.

Key: HIVE-2461
URL: https://issues.apache.org/jira/browse/HIVE-2461
Project: Hive
Issue Type: Improvement
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
I think a method added to PerfLogger to perform cleanup/final steps would be
very useful. For example, it could be used to close any database connections
created as part of a PerfLogger subclass, or to perform logging that requires
all perf values to first be calculated.
