Timer metric support.

[seanparsons]

Similar libraries like Ostrich and the Coda Hale metrics lib support the concept of timer metrics along with providing percentile, min, max and average data for those metrics. It would be really useful if ekg also supported those.

I think we should do this. It's on my agenda in the medium-term.

[hesselink]

Is this fixed by the Distribution metric type?

[tibbe]

Distribution does yet support percentiles (or other quantiles), as I want a better implementation than the one in statsd, which holds on to every data point. That approach doesn't scale well. Better is to keep a histogram of points and then doing a linear approximation in the histogram buckets.

[mtesseract]

Is somebody still on this? (Do you know, @tibbe?) Is there an implementation plan and/or work-in-progress somewhere? Would be interested in having distribution percentiles with ekg.

I'm not working on this, and I don't think @tibbe is, so patches welcome.
