Latency quantiles (in microseconds):
50.00 %ile +/- 5.00%: 2492
75.00 %ile +/- 2.50%: 3662
90.00 %ile +/- 1.00%: 4898
95.00 %ile +/- 0.50%: 6290
99.00 %ile +/- 0.10%: 12390

> Add toString for SampleQuantiles

> Project: Hadoop Common
> Issue Type: Improvement

> The new SampleQuantiles class is useful in the context of benchmarks, but
> currently there is no way to print it out outside the context of a metrics
> sink. It would be nice to have a convenient way to stringify it for logging,
> etc.
