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.
