Title:
  Unable to create server with image that has
  hw_watchdog_action='disabled'

Status in OpenStack Compute (nova):
  In Progress

Bug description:
  This is from ocata devstack. Set the hw_watchdog_action image property
  with value 'disabled':

  stack@osc:~$ openstack image set --property
  hw_watchdog_action=disabled cirros-0.3.4-x86_64-uec

  stack@osc:~$ openstack image show -c properties cirros-0.3.4-x86_64-uec
  +------------+------------------------------------------------------------------------------------------------------------------------------------+
  | Field      | Value                                                                                                                              |
  +------------+------------------------------------------------------------------------------------------------------------------------------------+
  | properties | hw_watchdog_action='disabled', kernel_id='08463073-3460-4b5f-92cc-ade974936e96', ramdisk_id='ff195fc4-c039-43b5-acca-501aba68aba2' |
  +------------+------------------------------------------------------------------------------------------------------------------------------------+

  Then try to boot the server and it will fail:

  stack@osc:~$ nova boot --poll --image c8af19ff-cebc-4112-a237-78dcd19e588c --flavor 42 test-watchdog-disabled
  ERROR (BadRequest): Invalid image metadata. Error: Field value disabled is invalid (HTTP 400) (Request-ID: req-488be9ab-ebcb-473b-b238-968f91ed0f48)

      Merge "Fix periodic-nova-py{27,35}-with-oslo-master"

  
  The problem is the ImageMetaProps object in nova is using enums for the hw_watchdog_action field:

  https://github.com/openstack/nova/blob/7a9eb10d0d15e5327aa73c72418d89afce11abef/nova/objects/fields.py#L383

  And that doesn't have 'disabled' as a value.

  However, if you look at the glance metadef it's an option, so someone
  using Horizon could set this:

  https://github.com/openstack/glance/blob/d3e820724e1d578003b13e72e753d9b1d75173e1/etc/metadefs
  /compute-watchdog.json#L25

  And the libvirt driver actually defaults to 'disabled':

  https://github.com/openstack/nova/blob/7a9eb10d0d15e5327aa73c72418d89afce11abef/nova/virt/libvirt/driver.py#L4536
