Print IP and port on cluster bus message sanity check (#11443) * Print IP and port on cluster bus message sanity check Add a print statement to indicate which IP/port is sending the error messages. That way we can at least check to see if it is a node in the cluster or some other nefarious nodes. It is proposed in #11339. Unrelated changes: the return check for connAddrPeerName should be -1 instead of C_ERR, although the value of C_ERR is also -1. Co-authored-by: Madelyn Olson 34459052+madolson@users.noreply.github.com
