Currently, the one-key script only accepts tar file generated by 'docker save' command, and the file name is hard-coded as following:

• kunlun_mysql.tar.gz
• kunlun_postgres.tar.gz
• kunlun_clustermgr.tar.gz

Also, the image name is also hard-coded as following:

• kunlun_mysql
• kunlun_postgres
• kunlun_clustermgr

We need to change this way, to allow using image url and also allow using specified file names. So that, the script can really be useful by users.

These should be supported in the config file, and generate_docker_script.py.

We add the following items in current config file in cluster:

  "images": {
      "kunlun-storage": "192.168.0.104:15000/kunlun-storage",
      "kunlun-server": "192.168.0.104:15000/kunlun-server",
      "kunlun-cluster-manager": "192.168.0.104:15000/kunlun-cluster-manager"
  },

Also, we add one option of --imageInFiles to support old way.

So, if the option is not provided, cluster.images must be specified. Otherwise, if the option is specified, we use the old way, no need to set cluster.images.

The remain issue is that, docker 19(server version) does not support the option of --pull always, we need to upgrade the docker version if necessary.

Otherwise, we need to do remove/pull first.
