KVM: implement GetShellCommandForConsole

This is a class method, because it calls _InstanceSerial, which is
another class method. The patch changes it to classmethod for all the
hypervisor classes.

KVM: classify _Instance{Monitor,Serial,KVMRuntime}

Those methods need nothing from the instantiated class, and just
manipulate strings, and fetch some class global variables, so they can
be classmethods.

Xen and KVM: correct a typo when checking args

A missing 'be' was present in the error string for both xen and kvm,
when the kernel or initrd path was not absolute.

KVM live migration: handle failure

If the KVM live migration ends up in a 'failed' state it has been
aborted at the kvm level, and the machine is still running locally.
We support also the 'cancelled' state even though there should be no way
of reaching it, without manual intervention....

KVM: instance migration

The tcp port used for migrating KVM instances is selectable at
./configure time. We use a single port as nodes are locked anyway during
a migration, so no two migrations can happen at the same time to the
same node.

KVM: add the _InstancePidAlive function

Throughout the kvm code we very often look for the instance pidfile
name, read it, and check if the process is alive. Abstract this into a
private function and use that one instead.

This patch also changes RebootInstance to check whether the instance is...

KVM: fix RebootInstance

RebootInstance was broken, because it just used to call StartInstance
with wrong parameters. With this patch we still stop the instance, but
use the saved kvm runtime to start it again.

KVM: retry the instance shutdown command

When we ask the instance to shutdown sometimes the command won't work,
especially if the instance isn't fully booted up. We'll wait for a bit,
and give it a few chances before giving up.

Xen: implement auxiliary migration functions

These are used, for the xen hypervisor, to copy the xen config file to
the remote node. This breaks migration for instances which have been
migrated, but not restarted, with the old code, for which the config
file was just lost....
