Kafka helm chart with SASL and authentication

[ljupcovangelski]

We need to improve the Helm chart for Kafka, to include options for encryption and authentication on the serer side, so that it can be deployed in another Kubernetes cluster on the Internet then the Airy Core components.

@ljupcovangelski The Kafka chart is bundled with the airy chart, right? In what scenario would the Kafka chart be installed in a different cluster?

Or let me put it differently: Hosting external Kafka's is better accomplished by picking a service or some other better maintained Kafka chart. It doesn't seem like this is part of our scope.

@chrismatix I agree it is outside of the scope of deploying Airy (which includes the bundles Kafka chart). However, as we do have the chart independent and it is possible to install Kafka separately in another place (namespace) and connect Airy to it, I think it is good that we include this functionality in the chart.

@ljupcovangelski yes makes sense. Thanks for clarifying
