  - Removed manual shutdown hook for hazelcast

    Shutdown hook for hazelcast are already working with spring boot. Just
    changed the policy to GRACEFUL (default is TERMINATE). This allow
    hazelcast to shutdown gracefully and recover from a rolling upgrade

    Also updated the Dockerfile to use multi stage to reduce by ~200Mb
    the docker image size.
