Title: Add logging for Rollup KPIs and perf metrics

- Adds a log line for every request that has the X-Soda2-Rollup header
- Adds standard performance metrics for every request through CodaHale Metrics (meters for every request type, histograms for request latencies)
- Adds histograms for non-rollup and rollup successful query latencies
- metrics are configurable - logging, JMX, and graphite reporters are all available
