KAFKA-19987: Add metrics from KIP-1216 to ops.html (#21130)
This commit adds the new thread-level rebalance listener callback
metrics from KIP-1216 to the Streams Monitoring section in ops.html:
- tasks-revoked-latency-avg and tasks-revoked-latency-max
- tasks-assigned-latency-avg and tasks-assigned-latency-max
- tasks-lost-latency-avg and tasks-lost-latency-max
All metrics are at the INFO recording level and measure time in
milliseconds.
