volumes are created without a name

[Jesse Andrews]

volumes created in the dashboard don't get a name

steps:

1) setup essex devstack (master) with ENABLED_SERVICES in your localrc including n-vol

  ENABLED_SERVICES=n-vol,g-api,g-reg,key,n-api,n-cpu,n-net,n-sch,n-vnc,horizon,mysql,rabbit,openstackx

2) login to dashboard, click "Instances & Volumes"
3) create a volume giving it the name horizon and size 1
4) on the devstack box source the openrc file:

    source openrc

5) create a volume via CLI

    nova volume-create --display_name=cli 1

6) look at dashboard volumes panel
7) run nova volume-list

Expected:

In horizon and cli you see 2 volumes, named cli and horizon

Actual:

In horizon and cli you see a volume named cli but no volume named horizon
