Interface ParquetMetricsCallback

@InterfaceStability.Unstable
public interface ParquetMetricsCallback

A simple interface to pass basic metric values by name to any implementation. Typically, an implementation of this interface will serve as a bridge to pass metric values on to the metrics system of a distributed engine (hadoop, spark, etc).
Development Note: This interface should provide a default implementation for any new metric tracker added to allow for backward compatibility
e.g.
default addMaximum(key, value) { } ;
