This patch introduces the option of changing an instance's nodes when doing the disk recreation. The rationale is that currently if an instance lives on a node that has gone down and is marked offline, it's not possible to re-create the disks and reinstall the instance on a different node without hacking the config file. Additionally, the LU now locks the instance's nodes (which was not done before), as we most likely allocate new resources on them.
