Is your feature request related to a problem? Please describe.

In the systemtests we use Strimzi Cluster Operator to create a Kafka cluster. The resource name is constant and the resource is always created in the same namespace (kafka). This makes debugging the tests quite hard.

Describe the solution you'd like

1. Create the kafka CR with unique name, and/or
2. Create the kafka CR in the empheremal per-test namespace (kafka-xxxxxx).

This would make correlating across pod-logs easiler.
