Major Description
In KafkaAssemblyOperator, when the rights to create ClusterRoleBindings are missing, we skip over the the error when they are not actually needed (i.e. when node port listeners or rack-awareness is not used). That allows users to install Strimzi without having the rights to create and ClusterRoleBindings.
However, in 0.20 we added the client rack awareness to Kafka Connect. And there we didn't handled the error in the same way so users which install Strimzi in the same way will not be able to run Kafka Connect.
