Print an error when kafka client threw exception multiple times #51
Description
We are running Logstash in quiet mode because Logstash can be really verbose.
In quiet mode, if the Kafka client can't connect, nothing is printed out.
It would be great to add an error message if the Kafka client threw an exception multiple times in a row (configurable ?). That way the quiet mode will hide intermittent failures but will print an error when there's possibly an unrecoverable issue.
