cman: Improve cman_tool startup error reporting
Several errors that can be generated by cman-preconfig get discarded and
replaced with a rather cursory and unhelpful
"corosync died: Could not read cluster configuration"
Now we print the messages passed back before examining the corosync
exit status.
