    Add 'disabled' to WatchdogAction field

    Image property hw_watchdog_action can have a 'disabled'
    value which is actually defined in the glance metadefs so
    someone using Horizon might pick that. Also, it's the default
    behavior in the libvirt driver. However, if you try to create
    a server with that set the create fails in nova-api because
    the enum field didn't have 'disabled' as a valid value.

    This adds it, bumps the ImageMetaProps version and adds tests.
