    …ss from existing when saving fails

In clusterSaveConfigOrDie, we will exit directly when saving
fails. In the case of disk failure, the cluster node will exit
immediately if there are some changes around the cluster.

Passive exit may bring unexpected effects, such as cluster down.
Provoide exit-on-cluster-config-file-save-error configuration
timen to control this behavior. Users who do not rely on nodes.conf
can actively migrate it later (or during low traffic periods).
