Ticket: https://issues.apache.org/jira/browse/KAFKA-18369 ## Summary This PR revises 4 DefaultStateUpdate metrics for Kafka Streams: - `idle-ratio` - `active-restore-ratio` - `standby-update-ratio` - `checkpoint-ratio` These metrics should represent the ratio of time spent on a certain action over a windowed duration, rather than an average of time spent ratio over iterations. This is implemented using a windowedSum aggregation for each of the 4 metrics, similar to https://github.com/apache/kafka/pull/21160 Each rolling window is controlled by 2 configs: 1. `metrics.sample.window.ms`: The window of time a metrics sample is computed over, default as 30 seconds. 2. `metrics.num.samples`: The number of samples maintained to compute metrics, default as 2. -- This is an automated message from the Apache Git Service.
