XD-3519: Rabbit Taps

Browse Source 
- instead of publishing to the default exchange, producers now publish to a topic exchange, to which the main queue is bound
- taps on a stream simply bind a queue to the same exchange with a name including the group for the tapping stream and a
    routing key pattern `#`
 - this means that multiple instances of the same tap stream will compete but multiple tap streams will get a copy
- for partitioned data, a single topic exchange is used, which each partition queue bound with its name as the routing key
 - this means taps on partitioned data see the consolidated messages

Remove unused binder utilities.

Use TopicExchange Always

Use a TopicExchange when binding a pubSub producer for consistency.

Remove Deprecated Binder Method

Add group to BindingProperties

- also fix artifact name in test support pom
- also fix some kafka tests (does not imply that kafka taps work - yet)
