    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.
