[2/3] git commit: updated refs/heads/master to 54d44eb
Add Apache Kafka event-bus support - producing only.
This commit produces event bus messages to a "cloudstack" topic
in Apache Kafka. Configuration is expected to be found in
/etc/cloudstack/management/kafka.producer.properties and will
generally be of the form:
bootstrap.servers=kafka-host1:9092,kafka-host2:9092
key.serializer=org.apache.kafka.common.serialization.StringSerializer
value.serializer=org.apache.kafka.common.serialization.StringSerializer
There is no way to parameterize the topic yet, and the consuming
code is just place-holder. I think adding a consumer within cloudstack
is very debatable and likely not needed.
