[PATCH] ctdb-config: depend on /etc/default/nodes file

[Rafael David Tinoco]

CTDB should start as a disabled unit (systemd) in most of the
distributions and, when trying to enable it for the first time, user
should get an unconfigured, or similar, error.

Depending on /etc/ctdb/nodes file will give a clear direction to final
user on what is needed in order to get cluster up and running. It should
work like previous ENABLED=NO variables in SySV like initialization
scripts.
