Issue Description

Type: feature request

Describe what feature you want

In some scenarios, due to some changes in the machine, such as IP changes, system configuration changes, etc., the K8s state of the node may be unavailable.

Similar to docker, if there is some problem with a container, using the (docker restart $container) command will actually reconfigure and restart the container without losing the persistent data, which can solve many misconfigure problems.

Therefore, I hope that sealer can also provide similar capabilities. When the above problems occur, simply executing a sealer restart command can correct the wrong configuration and repair the node to normal.
