[pve-devel] [PATCH cluster] Add warning for pvecm commands if not part of cluster

[Fabian Grünbichler]

If the cluster config file is missing, pvecm status, nodes
and expected will probably not work. Add a helpful warning
because the corosync-quorumtool error message is not very
descriptive here.
---
Already saw a couple of forum posts where users were
confused when pvecm status did not work after a fresh
installation, I think this would improve the situation.
Feel free to change the actual warning message if desired.
