  - node: works with local, docker
  - tomcat: works with download, docker
  - creates tmp dir
  - writes static and dynamic content into a config file (inside the tmp dir)
  - local/download: exports a Env-Var wich points to the new config file
  - docker: adds -e (Env-Var pointing to the config file) and -v (mounting the tmp dir) to docker

  config is like: {
    Name: "java.properties",
    Content: [

      { Line: "toldyouso.password=foobar", Regexp: "toldyouso.password=" },
