    Fix tag attribute disappearing in 2.33 and 2.37
    
    In the context of device tagging, bugs have caused the tag attribute
    to disappear starting with version 2.33 for block_devices and starting
    with version 2.37 for network interfaces. In other words, block
    devices could only be tagged in 2.32 and network interfaces between
    2.32 and 2.36 inclusively.
    
    This patch documents this behaviour in api-ref and introduces
    microversion 2.42, which re-adds the tag in all the right places.

Title:
  Microversion 2.37 break 2.32 usage

Status in OpenStack Compute (nova):
  Fix Released
Status in python-novaclient:
  New

Bug description:
  Device tagging support was added in microversion 2.32, as for
  ports:
  http://git.openstack.org/cgit/openstack/nova/tree/nova/api/openstack/compute/schemas/servers.py#n76
  but in latter microversion 2.37 accidentally removed it:
  http://git.openstack.org/cgit/openstack/nova/tree/nova/api/openstack/compute/schemas/servers.py#n82

  And for bdms:
  the schema is added by
  https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/block_device_mapping.py#L76
  and it will only work for microversion 2.32

  So this function is only usable from microversion 2.32 to 2.37 for
  ports and only for 2.32 for bdms.

  we should fix it and backport to Newton.
