    Use microversion 2.60 when attaching a multiattach volume
    
    Multiattach capable volumes can only be attached with microversion
    2.60 or later, so this checks if the volume being attached is
    multiattach capable and if microversion 2.60 is available, use it.

Title:
  unable to attach multiattach volume to server

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  The compute API 2.60 microversion allows attaching multiattach-capable
  volumes to server instances.

  However, when attempting to do so in Horizon it fails because Horizon
  doesn't specify microversion 2.60 during the attach call to nova (see
  screenshot).

  And you can see the error in the nova-api logs:

  [None req-9e43e495-a9ee-4460-85bb-1545ce1efbeb demo demo] Returning
  400 to user: Multiattach volumes are only supported starting with
  compute API version 2.60.

  Note that if Horizon is using python-novaclient for the attach volume
  call, it must have novaclient >= 10.1.0:
