      Description

      We may want to disable the features when benchmarking and etc, if the overhead of handling metrics degrades performance significantly (e.g., a large number of tasks).

      One possible way to do this:

      Change the MetricStore to an interface and provide an additional (optional) implementation that does nothing on method invocations (i.e., do not record any metrics). For example we can provide a JobConf option that enforces returning the dummy class on MetricStore#getStore, which seems to be the single point of access for using MetricStores.
