Please document shelving in VM state diagram

[Shaunak Kashyap]

The diagram on http://docs.openstack.org/developer/nova/devref/vmstates.html does not currently show the "SHELVED_OFFLOADED" state and the associated "shelve", "shelveOffload" and "unshelve" state transitions. Please update the diagram appropriately. Thank you.
