Title:
  duplicate property in server show for volumes

Status in python-openstackclient package in Ubuntu:
  New

Bug description:
  Description
  ===========
  Too many properties for volume attachments.
  volumes, attached_volumes and volumes_attached have same info, 
  we can have volumes and attached_volumes (in pretty format).

  
  Steps to reproduce
  ==================
  - Add 2 volumes to server  
  - Run openstack server show cmd 

   $ openstack server show demo_vm_2 --fit-width -c name, -c
  volumes_attached -c attached_volumes -c volumes


  Actual result
  =============

      +------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
      | Field            | Value                                                                                                                                                                     |
      +------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
      | attached_volumes | [{'device': None, 'id': '<_id>', 'volume_id': None, 'attachment_id': None, 'bdm_id': None, 'tag': None, 'delete_on_termination': False, 'name': None, 'location': None},  |
      |                  |   {'device': None, 'id': '<_id1>', 'volume_id': None, 'attachment_id': None, 'bdm_id': None, 'tag': None, 'delete_on_termination': False, 'name': None, 'location': None}]|
      | volumes          | [{'device': None, 'id': '<_id>', 'volume_id': None, 'attachment_id': None, 'bdm_id': None, 'tag': None, 'delete_on_termination': False, 'name': None, 'location': None},  |
      |                  |   {'device': None, 'id': '<_id1>', 'volume_id': None, 'attachment_id': None, 'bdm_id': None, 'tag': None, 'delete_on_termination': False, 'name': None, 'location': None}]|
      | volumes_attached | attachment_id=, bdm_id=, delete_on_termination='False', device=, id='<_id>', location=, name=, tag=, volume_id=                                                           |
      |                  | attachment_id=, bdm_id=, delete_on_termination='False', device=, id='322549da-aeb1-496d-9cbc-9cb6214640c1', location=, name=, tag=, volume_id=                            |
      +------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

  if above is not clear see here: https://paste.opendev.org/show/bVTSHATkNbIyS1mUDS9j/
  Here we have 3 properties for volume attachments, and they all have almost the same data, "volumes" is enough; it gives the data that's really required.


  
  Expected result
  ===============
  Something like nova client:

      | os-extended-volumes:volumes_attached | [{"id": "<_id>",
  "delete_on_termination": false}, {"id": "<_id>",
  "delete_on_termination": false}] |

  or only property for volumes.
