Settings when using Apache Kafka

If you want to use Apache Kafka, the environment variable names are converted with a prefix convention:

As an example:

environment:
  - KAFKA_RPC_BOOTSTRAP_SERVERS=192.168.1.1,192.168.1.2

This creates the file org.opennms.core.ipc.rpc.kafka.cfg with the content:

bootstrap.servers=192.168.1.1,192.168.1.2
