0a32edb94c
This change adds a new enum and field, VolumeAttachStatus and VolumeAttachStatusField, that will hold the constants for the 'attach_status' field of the VolumeAttachStatus object. This enum and field are based on the base oslo.versionedobjects enum and field. This also changes over the volume object to use the new field. Finally, all uses of strings for comparison and assignment to this field are changed over to use the constants defined within the enum.
