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

Forward port the live migration from 1.2 branch

This is forward port via copy (and not individual patches cherry-pick)
of the latest code on the 1.2 branch related to the migration.

The changes compared to 1.2 are the fact that we don't need the
IdentifyDisks step anymore (the drbd rpc calls are independent now), and...

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...
