clolov opened a new pull request, #14832: URL: https://github.com/apache/kafka/pull/14832
### Summary This pull request implements the first in the list of metrics in [KIP-963: Additional metrics in Tiered Storage](https://cwiki.apache.org/confluence/display/KAFKA/KIP-963%3A+Additional+metrics+in+Tiered+Storage). Since each partition of a topic will be serviced by its own RLMTask we need an aggregator object for a topic. The aggregator object in this pull request is `BrokerTopicAggregatedMetric`. Since the RemoteCopyLagBytes is a gauge I have introduced a new `GaugeWrapper`. The GaugeWrapper is used by the metrics collection system to interact with the BrokerTopicAggregatedMetric. The RemoteLogManager interacts with the BrokerTopicAggregatedMetric directly. -- This is an automated message from the Apache Git Service.
