Breakerbox 0.2.6

• Tenacity 0.6.9
• Switch from using latency_execute to latency_total for percentile metrics. The latency_execute is a closer measurement to successful execution times. Where latency_total is more accurate at the actual time the application is experiencing for successful and timed out commands. Since we assume breakerbox is used more in a debugging response and investigations rather than profiling/benchmarking, latency_total is more helpful in those quick response situations. In comparison when evaluating if your threadpool sizes and timeouts are set appropriately it is better to look at a historical trend of the latency_execute metric.
