Description
In the `io_load_listener` logs we print out the admission `bypassed` requests, which represent below-raft writes that bypassed AC. It is a good indicator of replication writes that were not subject to AC. We get frequent escalations where replication writes on older versions overload the cluster. So having this metric readily available would help to quickly identify that a version upgrade would help.
