Currently this feature is hypervisor specific, but under kvm we use it
by default (aka: if the user hasn't specified another network script
which overrides our auto-generated one) to specify the routing table.
This was already hinted as a possibility in the manpages, but never
explicitely stated as a reality, so we update gnt-cluster(8) to actually
say this, and gnt-{backup,instance}(8) to point to gnt-cluster(8) for
more information.

Currently ‘gnt-backup export’ always returns exit code zero, even in the
face of complete failure during backup (only failure to stop/start the
instance will cause job failure and thus non-zero exit code). This is
bad, since one cannot script the backup.

This patch adds some simple results from the LU so that the command line
script can return good exit code. It will:
  - return zero for full success (snapshot removal errors are ignored
    though)
  - return one for full failure (finalize export failure or all disks
    failure)
  - return two for partial failure (some disks backed up, some not)

Currently we have both a default_hypervisor and an enabled_hypervisors
list. The former is only settable at cluster init time, while the latter
can be changed with cluster modify.

This becomes cumbersome in a few ways: at cluster init time for example
if we pass in a list of enabled hypervisors which doesn't include the
"default" xen-pvm one, we're also forced to pass a default hypervisor,
or an error will be reported. It is also currently possible to disable
the default hypervisor in cluster-modify (with unknown results).

In order to avoid this we get rid of this field altogether, and define
the "first" enabled hypervisor as the default one. This allows ease of
changing which one is the default, and at the same time maintains
coherency.

At configuration upgrade we make sure that the old default is first in
the list, so that 2.0 cluster defaults are preserved.

This (somewhat big) patch adds support for remotely rebooting the nodes
via whatever support the hypervisor has for such a concept.

For KVM/fake (and containers in the future) this just uses sysrq plus a
‘reboot’ call if the sysrq method failed. For Xen, it first tries the
above, and then Xen-hypervisor reboot (we first try sysrq since that
just requires opening a file handle, whereas xen reboot means launching
an external utility).

The user interface is:

    # gnt-node powercycle node5
    Are you sure you want to hard powercycle node node5?
    y/[n]/?: y
    Reboot scheduled in 5 seconds

The node reboots hopefully after sending the reply. In case the clock is
broken, “time.sleep(5)” might take ages (but then I suspect SSL
negotiation wouldn't work).
