Properly report metrics to datadog with the appropriate tags
...
This requires a much more recent version of our metrics-datadog library but
does result in the right values being reported into datadog.

Major refactor to support dropwizard-metrics as the means of outputting metrics
...
This commit changes the structure of Verspaetung pretty dramatically to allow
for the registering of Gauges for the various offsets
With this change the KafkaPoller is pushing the latest offsets into a map and the
ZK consumer tree watchers are pushing consumer offsets into a separate map.

Hack together the actual delta reporting, UNCLEAN CODE ALERT

Still very much in the experimental phase, need to refactor KafkaPoller a lot
at this point and decide which code should live where and give it plenty of

Exploratory testing, a veritable boatload of garbage and hacks

This will at least create some stupid consumers and try to fetch the latest

Introducing the BrokerTreeWatcher to track changes to the broker list in Zookeeper

This commit includes a lot of work in progress kind of code. STill
experimenting with how to bind the events from the Zookeeper event-driven
system, in with the KafkaPoller busy-wait-loop system.

Introduce TopicPartition for acting as a Hash key for (topic, partition_id) tuples
...
This means the consumersMap that we're going to keep track of will have the key
of a TopicPartition, e.g.: ConcurrentHashMap<TopicPartition, List<ConsumerOffset>>
When we receive the data from the Kafka meta-data calls (to be added) all we'll
need to do is create the right TopicPartition and walk the list of
ConsumerOffset instances to start reporting metrics
