Prior to rke v0.2.0, RKE saves the cluster state which consists of the cluster configuration file `cluster.yml` and components certificates in kubernetes cluster as secrets, in v0.2.0 RKE creates a `.rkestate` file in the same directory that has the cluster configuration file, this file contains the current state of the cluster including the RKE config and the certificates, it is essential to keep this file to be able to update the cluster or perform any operation on it.
