[REEF-1732] Build Metrics System (#1460)

Enhance the capabilities of MetricService by adding the following functionality:
   * Let the user specify the type of the metric, as opposed to being restricted to Counters.
   * Let the user maintain a timeseries and keep track of the history of updates for a given metric.
   * Add example implementations and functional tests to demonstrate usage.
