statsd histogram to support more than 1 second

statsd histogram to support more than 1 second

Summary:
Problem: Collectd/Statsd supports configurable percentiles for timers but it limits the value to be 1 to 1000ms. If the timer value is more than 1000ms, it uses for min, max, average,... and drops it for percentile computation.

Solution: Added support for increasing bin width when the value is above histogram's range.

Test Plan: Tested by sending metrics within range and out-of-range (ie above 1000 ms)
