Dropwizard metric emitter for druid metrics

[rohitkochar]

A new metric emitter which would convert the druid metrics into corresponding dropwizard metrics(http://metrics.dropwizard.io/3.1.0/) and then use various emitters of dropwizard like statsd,http,console,jmx etc to emit the metrics to various sinks.
Dropwizard is widely used metric collection library and already has emitters to lot of metric stores.
