KAFKA-3857 Additional log cleaner metrics Fixes KAFKA-3857 Changes proposed in this pull request: An additional log cleaner metric has been added: time-since-last-run-ms: Time since the last log cleaner run, in milliseconds. This metric would be reset to 0 every time log cleaner thread runs. If this metric keeps constantly increasing, it indicates that the log cleaner thread is not alive. If you are creating alerts around log cleaner, you could monitor this metric. A high "time-since-last-run-ms" value (eg: 600000) indicates that the log cleaner hasn't been running since the last 10 minutes. The code has been tested. JMX metric has been verified.
