Improve WSREP's "Failed to report last committed" warning message

Details

    Description

      When a Galera Cluster is under a lot of load, it's common for the log to have warning messages like:

      [Warning] WSREP: Failed to report last committed 211651504, -4 (Interrupted system call)

      or

      [Warning] WSREP: Failed to report last committed 342386158, -110 (Connection timed out)

      "Failed to report last committed" sounds like a serious problem, but I've been told that these warnings don't necessarily mean that anything has gone wrong. It usually just means that the cluster is under a lot of load.

      Can we improve this warning, so that the meaning is easier for users and DBAs to understand?
