Title: Add m1/m5/m15 meter ported from yammer metrics

This patch adds a meter stat using exponentially weighted moving averages to supply 1/5/15 minute load averages. Rates are currently per second. Ported almost verbatim from Yammer metrics.

Starts a ticker thread on import, so has been placed in greplin.scales.meter for isolation.
