Title:
  Hyper-V agent IDE/SCSI related refactoring necessary

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Hyper-V Server 2012 R2 introduces a new feature for virtual machines
  named "generation 2", consisting mainly in a new firmware and better
  support for synthetic devices.

  Generation 2 VMs don't support IDE devices, which means that local
  boot, ephemeral disks and DVD Drives must be attached as SCSI, instead
  of IDE for generation 1 VMs.

  Since the Virtual Hard Disks and Virtual CD/DVD Disks can be attached
  to IDE controllers or SCSI controllers (generation 2 only), some
  constants, variables and methods have been improperly named, having
  the IDE prefix.

  e.g.: _IDE_DISK_RES_SUB_TYPE will have to be renamed to
  _HARD_DISK_RES_SUB_TYPE
