This code does not need to run as root, therefore it's better to split
it out. It is now run with the same permissions as the master daemon.

This addresses issue 230: passing two methods of booting to KVM can,
depending on the KVM version, confuse it.

Note that commit 4304964a introduced a partial fix for this (but only
for disks, and keyed on KVM versions). However, it didn't fix cdrom
booting, which still fails with the same error, so let's fix it more
generically; we still leave the per-disk check since that is about
-boot c versus -drive …,boot=on rather than two boot methods.

Patch is based on the one submitted by Vladimir Mencl, many thanks!

This uses confd to query the DRBD minors, which is very special; no
other command currently does so.

Since the backend is only implemented in the Haskell version of confd,
we have checks that 1) confd is enable, and 2) hs confd is also
enabled. If by mistake people do manage to query Python confd, the
error message will be clean:

  Query gave non-ok status '2': not implemented

So nothing breaks in an "ugly" way.

This derives from an internal bug, but the story is consistent across
both internal and external usage of hbal.

Basically right now, hbal returns exit code 1 if requested to exit
early, even if all jobs are successful. This is counter-intuitive due
to two reasons:

- hbal did what it was requested (exit early), so it shouldn't return error
- there were no job failures, so there's nothing to "cleanup" or
  investigate on the Ganeti cluster, so again it shouldn't return
  error

Therefore the new behaviour is as follows:

- for cases where all jobs were successful, even if terminated early
  via SIGINT or via --limit, we exit with code 0
- for cases where jobs have failed or there were other errors in
  running hbal, the exit code is 1
- for cases were hbal is requested an immediate termination (SIGTERM),
  exit code is 2, denoting "unknown whether the Ganeti cluster is
  consistent or not"

Backtracking through git blame, it turns out than commit 49148d15

To change the cluster from single homed to multi homed or vice versa one
must target the master node first, and pass the --force option. All
other nodes then will work as long as they are reachable by the master.

Note that this will also prevent a node to be set to single-homed if the
master is multi-homed, which wasn't disallowed before, and warn if a
single-homed <-> multi-homed transition happens.

Also note that it's still theoretically possible to flip a cluster
inadvertently by changing the master node this way, and then doing a
master failover before fixing the other nodes.
