Review request for hive and Ning Zhang.
Summary
-------
I created a new class PerfLogger, which wraps the old functionality of
Utilities' PerfLogBegin and PerfLogBegin methods. I also added a config
variable hive.exec.perf.logger. The value of this variable can be changed to
point to a subclass of PerfLogger which can customize the code in PerfLogBegin
and PerfLogEnd.
This addresses bug HIVE-2364.

Testing
-------
I ran the code as it is and made sure it continued to log the performance
messages as before.
I also created a subclass of PerfLogger and used its class name as the value of
hive.exec.perf.logger, and verified the subclass's code was run.
Thanks,
Kevin

> Currently, the way we measure the length of time spent by a piece of code is
> using the methods PerfLogBegin and PerfLogEnd in the Utilities class. If we
> made the class responsible for logging this data configurable, it would allow
> for more flexibility, in particular, we would not be restricted to logging to
> an Apache Commons Log.
