Actually mark drives as read-only if so configured

This patch correctly marks the drives as read-only for Xen, and raises
and exception for KVM since it doesn't support read-only drives.

KVM and Xen: add the HV_ROOT_PATH parameter

This parameter allows a different path to be passed to the instance
kernel. The new parameter is mandatory, and by default has the value of
the old hardcoded value for both kvm and xen.

Beta1 clusters will need to have this parameter added for their...

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.

KVM: save and remove the KVM runtime

At instance startup time we save the kvm runtime, and at stop time we
delete it. This patch also includes a function to load the kvm runtime,
which is unused yet.

KVM: split KVM runtime generation and startup

Before we used to generate the kvm command line and then just run it.
With this patch we split the generation from the time it is run,
allowing us to save it and replay it at reboot.

KVM: add a _CONF_DIR

Currently we keep pid files and control files. In the conf dir we'll
also keep the data to start the instance anew, and the network
interface scripts. These will then be copied to a separate area (since
_CONF_DIR could be mounted 'noexec') and used to start the instance....

Simplify hypervisor block_devices structure

This is a partial forward-port of commit 1136 on the 1.2 branch:

The hypervisor doesn't need to be passed the whole block device
  structure, so we'll just give it the block device name on the local
  node, and the name as seen by the instance. This will make it easier to...

Add KVM hypervisor code

ht_kvm.py contains the code for ganeti to work under kvm.
This patch also modifies Makefile.am to ship that file, and
lib/hypervisor/__init__.py to import it, and add kvm to the
