PerformanceEvaluation: Report aggregate timings on a single line
----------------------------------------------------------------

                 Key: HBASE-5527
                 URL: https://issues.apache.org/jira/browse/HBASE-5527
             Project: HBase
          Issue Type: Improvement
          Components: performance
    Affects Versions: 0.92.0
            Reporter: Benoit Sigoure
            Assignee: Benoit Sigoure
            Priority: Minor
         Attachments: 0001-PerformanceEvaluation-fixes.patch

When running {{PerformanceEvaluation}} with {{--nomapred}} it's hard to locate all the lines
saying {{Finished 14 in 292979ms writing 2000000 rows}} in the output.  This change adds a
couples line to summarize the run at the end, which makes parsing and scripting the output
easier:
{code}
12/03/06 00:43:58 INFO hbase.PerformanceEvaluation: [RandomWriteTest] Summary of timings (ms):
[15940, 15776, 15866, 15973, 15682, 15740, 15764, 15830, 15768, 15968, 15921, 15755, 15963,
15818, 15903, 15662]
12/03/06 00:43:58 INFO hbase.PerformanceEvaluation: [RandomWriteTest]	Min: 15662ms	Max: 15973ms
Avg: 15833ms
{code}

Patch also removes a couple minor code smells.
