Volume-transfer Creation doesn't support 'name' specified via xml format

[wingwj]

Volume-transfer creation provides to specify the 'name' param in cinder.

I tested it on json format, everything's ok.
But when I create it on xml format, the 'name' param is not transmitted to Cinder.

--------------
Here is input-body of my test:

    <transfer name="transfer6" volume_id="8d37404a-4d60-466c-a8b8-78501db208da"/>

Here's the result, you can found the 'name' is 'None' in response.

<?xml version='1.0' encoding='UTF-8'?>
<transfer
    xmlns:os-volume-transfer="http://docs.openstack.org/volume/ext/volume-transfer/api/v1.1" auth_key="9266c59563c84774" created_at="2013-10-23 07:59:07.231575" id="7e7d872b-791a-40a6-887f-9b718b4e04b0" name="None" volume_id="8d37404a-4d60-466c-a8b8-78501db208da"/>
--------------

The reason is due to the inconsistent processing between xml and json.

The CreateDeserializer of xml-format uses 'display_name' param, not 'name':
        --> attributes = ['volume_id', 'display_name']
But the processing of create() in volume-transfer, uses 'name' not 'display_name':
        --> name = transfer.get('name', None)

Therefore, no matter the 'name' is specified, its value in response will also be 'None'.

    Transfer creation doesn't support 'name' via xml

    Change the transfer create XML deserializer to use 'name' rather than
    'display_name'. This is in line with cinderclient and the json code.
