Horizon fail to view volume data if configured with cinder v2

[zhu zhu]

When Horizon configured with using cinder v2 api as below:
OPENSTACK_API_VERSIONS = {
    "identity": 2.0,
    "volume": 2
}

Note that: Nova already switch to use cinderv2 api as default since commit:
https://review.openstack.org/#/c/124468

After nova attach a volume(with configured nova using cinder_catalog_info="volumev2:cinderv2:publicURL'. Login into horion,
it will fail to get to the instance detail pages due to error blow.

It should be noted that the cinder v2 api. volume detail API response will be different from v1 apis. Hense display_name will not exist for v2 responses.
