Add JSON output and looping options to ConsumerOffsetChecker
------------------------------------------------------------
Key: KAFKA-313
URL: https://issues.apache.org/jira/browse/KAFKA-313
Project: Kafka
Issue Type: Improvement
Reporter: Dave DeMaagd
Priority: Minor
Adds:
* '--loop N' - causes the program to loop forever, sleeping for up to N seconds
between loops (loop time minus collection time, unless that's less than 0, at
which point it will just run again immediately)
* '--asjson' - display as a JSON string instead of the more human readable
output format.
Neither of the above depend on each other (you can loop in the human readable
output, or do a single shot execution with JSON output). Existing
behavior/output maintained if neither of the above are used. Diff Attached.
