Hyper-V Instance rescue support
The Hyper-V Nova driver is currently not supporting Nova "rescue" commands,
unlike other hypervisor drivers (e.g. libvirt).
The Hyper-V Nova driver can be extended to support the "rescue" feature,
supporting both Linux and Windows images.
Hyper-V uses VHD/VHDX images, not AMI/AKI/ARI. The Nova rescue command will
result in a new temporary image spawned using the same image as the instance to
be rescued, attaching the root disk of the original image as secondary local
disk.
The "unrescue" command will result in the temporary instance being deleted and
the original instance restarted.

Spec for instance rescue support in Hyper-V
Based on the new rules, we don't need a spec for this, and it makes sense from a driver parity point of view, so approved. --johnthetubaguy (8th October 2014)
Not enough positive reviews on this code yet, moving to kilo-2 --johnthetubaguy 17th December 2014
