Flag to post counts to kafka/Control number of message decode exceptions printed

Added flag to control posting of counts to kafka audit.
This is done by setting 'post.tracking.counts.to.kafka' to true or false in the configuration file.
Defaults to true.

During decoding of messages, exceptions were being printed for all records of a topic.
The number of exceptions printed can now be controlled by setting the 'max.decoder.exceptions.to.print' in the configuration file.
Defaults to 10.
