We need to make this project supported:
https://github.com/camunda/camunda-external-task-client-spring-boot/

Therefor we should probably best merge it into the existing Spring Boot Starter.

Background: We push people more towards the ET pattern as default development model, even if they use Spring Boot. So it needs to be as easy as use a JavaDelegate.
Using this model makes the solutions people build much more robust for possible architectural changes
