Make percentiles for dogstatsd configurable

[alq666]

1. etsy's statsd only computes the 90th by default but allows configurable percentiles
2. our current 50, 75, 85, 95, 99 is probably too many by default
3. our initial average was the median; it's deployed widely

My vote goes for default metrics goes to:

• max
• count
• avg
• median
• 95% (2 sigmas of normal distro), most people currently use this one.

min is of unclear usefulness so far. If it's measuring time, min always ends up near 0.

5 metrics instead of 8 with average and median

Note for future reference: if we make it configurable, it would be good to
have the front end "know" about it or have a way to guess it, so we can
automatically generate min + med + "top" graphs.

More flexibility/configurability => more complicated for the front-end to
automatically show the right thing.
