The upgrade of a Ganeti cluster is done in several
high-level steps ("Draining queue", "Pausing the watcher",
"Stopping daemons", ...). Log those headings as well in
order to simplify reading the log file; with these headings,
it is more easy to understand which goal is aimed for with
all the micro-step RunCmd log entries.
