Added a framework for metrics
Added a metrics framework based on the codahale Metrics
package. ONOS can create a registry and maintain Metrics,
as well as dump out metrics values via a REST API. Unit
tests are include that test the REST APIs. Currently
supports Timers, Counters, Gauges, Meters, and Histograms.
