Description

A typical SLRP configuration could look like the following:

{
  "type": "org.apache.mesos.rp.local.storage",
  "name": "local-volume",
  "storage": {
    "csi_plugins": [
      {
        "name": "plugin_1",
        "command": {...},
        "resources": [...],
        "container": {...}
      },
      {
        "name": "plugin_2",
        "command": {...},
        "resources": [...],
        "container": {...}
      }
    ],
    "controller_plugin_name": "plugin_1",
    "node_plugin_name": "plugin_2"
  }
}

The csi_plugins field lists the configurations to launch standalone containers for CSI plugins. The plugins are specified through a map, then we use the controller_plugin_name and node_plugin_name fields to refer to the corresponding plugin. With this design, we can support both headless and split-component deployment for CSI.
