Review Comment:
   The zk broker waits for the metadata update before returning a response to 
the `ElectLeader` request, whereas the Kraft broker does not. Consequently, the 
Kraft broker does not need delayedOperation metrics for ElectLeader requests. 
Instead, kraft broker has `ForwardingManager` metrics to monitor the forwarded 
requests.
