Add Spring Boot Actuator to provide health endpoint

Signed-off-by: schuberr robert.schubert@msg.group

Current situation: for a helm deployment no actuator endpoints are available.

Target situation: For readiness probes in a k8s deployment (as well as a local running docker application) we want to have exposed health endpoints: readiness: path: /actuator/health liveness: path: /actuator/health startup: path: /actuator/health

Solution: add the spring-boot-starter-actuator dependency.
