   "steps": [
    {
      "step_name": "exec_task", // The name of the step, which matches the value of CurrentStepName.
      "action_info": {    // The actions supported for this step.
        "Waiting": [      // The status, which matches the value of Status.
          "modifySwitchTime" // The action. Multiple actions are supported.
        ]
      }
    },
    {
      "step_name": "init_task", // The name of the step.
      "action_info": {    // The actions supported for this step.
        "Running": [      // The status.
          "cancel",       // The action.
          "pause"
        ]
