Description
When a client's authentication token expires, upon connecting to a master or tserver, the result is that the Kudu server logs a warning message about an unauthenticated connection attempt. It would be nice if these connections were quantified as a metric instead, particularly in cases where there are a large number of these messages.
Note: this would be particularly helpful when users are using older versions of the Java client, that may not reauthenticate automatically, leading to a huge amount of warning messages in the logs.
