This commit restructures the cloud messaging group by removing binder specific checkbox for Spring Cloud Bus and Spring Cloud Stream. A new "Messaging" group is added with RabbitMQ, Kafka and JMS. To create a new cloud messaging project, the user should now select the technology and a binder. To support Spring Cloud Stream with Kafka streams, a dedicated "Kafka Streams" has been introduced. Closes gh-557
