The Taint plugin does not work

[ilyndon]

What happened:

allinone环境，尝试使用Taint插件去除master污点，根据官方文档，Clusterfile配置如下：

apiVersion: sealer.cloud/v2
kind: Cluster
metadata:
  creationTimestamp: null
  name: my-cluster
spec:
  hosts:
    - ips: [ 172.26.198.3 ]
      roles: [ master ] # add role field to specify the node role
  image: helm-dash-ingress-redis:v1
  ssh:
    user: root
    passwd: P@ssw1rd
    port: "22"
---
apiVersion: sealer.aliyun.com/v1alpha1
kind: Plugin
metadata:
  name: taint
spec:
  type: TAINT
  action: PreGuest
  data: |

---
apiVersion: sealer.aliyun.com/v1alpha1
kind: Plugin
metadata:
  name: MyLabel
spec:
  type: LABEL
  action: PreGuest
  data: |
    172.26.198.3 envnode=xiot
---
apiVersion: sealer.aliyun.com/v1alpha1
kind: Plugin
metadata:
  name: checkCluster
spec:
  type: CLUSTERCHECK
  action: PreGuest

部分运行日志如下：

运行完成后查看master节点信息：

`kubectl describe node ems8
Name:               ems8
Roles:              control-plane,master
Labels:             beta.kubernetes.io/arch=amd64
                    beta.kubernetes.io/os=linux
                    envnode=xiot
                    kubernetes.io/arch=amd64
                    kubernetes.io/hostname=ems8
                    kubernetes.io/os=linux
                    node-role.kubernetes.io/control-plane=
                    node-role.kubernetes.io/master=

`

可以看到，Label插件可以正常生效，但是Taint插件未生效。describe查看节点，还存在污点node-role.kubernetes.io/master:NoSchedule，麻烦看下配置是否有问题？
