MetricGroup
MetricRegistry MetricGroup is a class responsible for metrics registering, there is a metrics container in it. It provides register method for each type of measurable metric, registering metrics will put metrics to the metrics container.

MetricsReporter
MetricsReporter is used to report metrics to external backend, Paimon will implement an out of box reporter as JMX `MetricsReporter`.
