Control Bus Management

The SpEL and Groovy support for Control Bus EI pattern has been removed in favor of less invasive Control Bus Management via ControlBusCommandRegistry (and supplemental ControlBusController REST endpoint at /control-bus). The <control-bus> XML component now fully relies on the ControlBusCommandRegistry functionality. The DSL's controlBusOnRegistry() is deprecated now in favor of controlBus() which does now exactly the same and fully relies on the ControlBusCommandRegistry functionality.

Paho MQTT as optional dependency

The org.eclipse.paho:org.eclipse.paho.client.mqttv3 dependency for spring-integration-mqtt is now also optional as org.eclipse.paho:org.eclipse.paho.mqttv5.client always was. So, depending on the target project requirement for MQTT protocol version support, this or that dependency has to be included.
