cluster: prohibit the clean operations during scale-out

[srstack]

What problem does this PR solve?

prohibit the clean operations during scale-out

Because the clean operation will stop the cluster, if the cluster is stopped while the scale-out is not completed, the scale-out will be abnormal.

What is changed and how it works?

Will check the scale-out file lock before clean
