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....

Implement the new live migration backend functions

MigrationInfo, AcceptInstance and AbortMigration are implemented as
hypervisor specific functions, and by default they do nothing (as
they're not always necessary).

This patch also converts hv_base.MigrateInstance docstring to epydoc,...

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.

We must take special care about instance nics:...

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....

KVM: Remove sockets after shutdown

Abstract the monitor and serial socket naming in two functions, and
reuse them to cleanup the files after shutdown.
