I've had an offline chat with @StephanEwen and as a result updated the PR.
List of changes:
* dropped Meters, Histograms and Timers
* we weren't convinced that the performance of the implementation used is
efficient enough for our use-cases
* removed Reservoir/Snapshot and various wrapper classes
* moved ScheduledDropWizardReporter into a new flink-metrics-dropwizard
module within flink-metrics
* removes Dropwizard usage entirely from flink-core
* the MetricRegistry no longer maintains maps of all metrics; reporters are
from now on responsible for doing this
* Listener interface was removed
* AbstractReporter class was added that implements this behaviour
* will make it easier to support multiple reporters in the future
* Counter and Gauge no longer implement the DropWizard interface
* added Counter-/GaugeWrapper classes for DropWizard reporters
