use healthcheck and resources in compose

[bgruening]

It would be nice to upgrade our default compose file to include healthcheck and more resources. If we upgrade kompose and use the new 1.2 release we could also use this features in k8s.

    healthcheck:
      test: ["CMD", "echo", "helloworld"]
      interval: 1m30s
      timeout: 10s
      retries: 3
    deploy:
      replicas: 6
      resources:
        limits:
          cpus: '0.001'
          memory: 50M
        reservations:
          cpus: '0.0001'
          memory: 20M
