Description

currently when a kafka client fails to connect to a cluster, users see something like this:

Connection to node -1 terminated during authentication. This may indicate that authentication failed due to invalid credentials. 

that log line is mostly useless in identifying which (of potentially many) kafka client is having issues and what kafka cluster is it having issues with.

would be nice to record the remote host/port
