Description

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:

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

Patch also removes a couple minor code smells.
