AITFIVE-203 kafka crawl log feed
fix log messages to say "kafka"
switch to org.apache.kafka.clients.producer.KafkaProducer to see if we can avoid the InterruptedException at the end of the crawl (and log warnings on failure to send message)
logging improvement
only release the lock if we actually own it (avoid java.lang.IllegalMonitorStateException at java.util.concurrent.locks.ReentrantLock.tryRelease(ReentrantLock.java:155))
new style kafka configuration properties
so that it can appear in the crawl log, add contentSize to CrawlURI extraInfo, for http transactions (the only case in heritrix currently where contentLength and contentSize differ)
Merge branch 'extra-info-size' into aitfive-203
for kafka/amqp crawl log feeds, remove now redundant contentSize from extraInfo
Merge branch 'aitfive-203' of github.com:nlevitt/heritrix3 into aitfive-203
