Adjust the project for openshift deployment
    
    - Add a Dockerfile to build the project
    - Add an entrypoint.sh file called when starting the project in openshift
    - Hide password from the logs if the command failed
    - Do regular prints in openshift so the lines show in the logs
      (triggered via an environment variable)
