Bug 1081703

+++ This bug was initially created as a clone of Bug #1035790 +++

Description of problem:

cinder endpoint v2 changed the volume names attr to --name instead of --display-name.

when I change the cinder endpoint to v2 and create volumes, horizon crashes when we try to query the volumes

Version-Release number of selected component (if applicable):

python-django-horizon-2013.2-5.el6ost.noarch

How reproducible:

100%

Steps to Reproduce:
Run the following in cli:

1. install openstack with packstack
2. change cinder's endpoint in keystone to v2:

keystone endpoint-create --region RegionOne --service-id 10fd33fdca4f4ca4a2e21c2c786a3495 --publicurl 'http://<ip>:8776/v2/%(tenant_id)s' --adminurl 'http://<ip>:8776/v2/%(tenant_id)s' --internalurl 'http://<ip>:8776/v2/%(tenant_id)s'

delete the old v1 endpoint:

keystone endpoint-delete <endpoint that uses v1>

3. create a volume using v2 API:

OS_VOLUME_API_VERSION=2 cinder create 10 --name <name>

4. log in to horizon -> project -> volumes

Actual results:

Horizon gives an attr error on name

Expected results:

we should be able to query both v1 and v2 attr. 
but if not we need a clear error and not an attr error.

How to test (copied from blueprint's whiteboard in case it gets lost):

In the local settings, set 'volume' in OPENSTACK_API_VERSIONS to 1 or 2 depending on the version you want to test.

OPENSTACK_API_VERSIONS = {
    "volume": 2
}

If your debug levels are set, you should be able to verify that the cinderclient calls are using the appropriate v1 or v2 URL.

Panels of interests:
* Volumes: All the volume actions should still work using either v1 or v2
* Images & Snapshots: Volume snapshots actions should work using v1 and v2
* Instances: Create instance has several options related to volumes and booting from volumes, these should still work and the volumes or volume snapshots displayed correct
* Admin - Volumes: Should display correctly, no changes for volume types which are still expected to work with both versions.

The name display was also generally improved so that the volume id is always shown if the volume doesn't have a name.
