* Upgrade to Apache Kafka 0.10.1.1 * Upgrade to AssertJ 2.6 * Upgrade to Gradle 3.3 * Upgrade to spring-io-plugin 0.0.6 * Upgrade to JaCoCo 0.7.8 * Upgrade to SF 4.3.5 * Short polishing in `build.gradle` for redundant dependencies * Move `MessagingMessageListenerAdapterTests` to the proper package Mostly just upgrade. Looks like AssertJ `2.5` just has binary incompatibility with `2.6. Tested against IO `Brussels` without any problems
