SKS-3327: Improve root partition expanding commands in preKubeadmComm…

…ands (#192)

ticket
-
[\[SKS-3327\] 原地更新 - ARM的集群，磁盘扩容，原地更新失败 -
Jira](http://jira.smartx.com/browse/SKS-3327)
#191 只修改了
playbook，在创建节点时指定大于模板大小的磁盘还需执行 preKubeadmCommands 中的命令。

changes
-
- 优化 templates/cluster-template.yaml 中 preKubeadmCommands
提示的扩容分区命令，适配更多不同的操作系统
