crowbar-pacemaker: don't tell systemd to enable drbd (bsc#971771)

https://bugzilla.suse.com/show_bug.cgi?id=971771 We only want DRBD started by Pacemaker, with the possible exception of during initial DRBD setup. If it gets started by systemd, systemd will believe it owns the service, in which case during system shutdown it will prematurely shut down DRBD without regard for any of the other services and resources depending on it. Instead we want Pacemaker to stop things in the correct order, even taking care of inter-node dependencies. This fix will not be sufficient by itself, since we still need to address: https://bugzilla.suse.com/show_bug.cgi?id=980341 Thanks to Adam Spiers <[email protected]> (for the fix & for writing the commit message)
