Docker files for alarm server

[georgweiss]

After som trials and errors.... Docker for the alarm service comes with some limitations. I have created three files to cover the use cases:

• Run only Zookeeper and Kafka. Saves user from downloading and configuring Kafka.
• Run the entire stack to import a configuration, only for default topic "Accelerator"
• Run the entire stack in "normal mode", only for default topic "Accelerator"

Peer testing and feed-back appreciated.

Is there a reason you closed this PR?

Yes, I realized there might be a better strategy:

1. Docker compose bundling Kafka/Zookeeper, Elastic and MongoDB. This would then be common for all middleware services.
2. Docker compose for the individual middleware services.

Will create a new PR when I have verified this scheme.

yup that makes perfect sense...
docker compose for middlelayer backends... this would make networking much easier
