barbican's secret_ref created by nova misses barbican version

[Jeremy Liu]

I created a volume in cinder which was encryped with barbican.
Then I tried to attach this volume to a vm using command "nova volume-attach vm2 15d7b84a-9f08-4aac-9fcf-495ede08593c /dev/vdc", it failed.
After debugging, I found the secret_ref created in nova was wrong.
The secret_ref returned here https://github.com/openstack/nova/blob/stable/mitaka/nova/keymgr/barbican.py#L308 was "http://controller:9311/secrets/00000000-0000-0000-0000-000000000000".
In fact, it should contain barbican version number "v1", which means the secret_ref should be "http://controller:9311/v1/secrets/00000000-0000-0000-0000-000000000000".
My dev env is "stable/mitaka".
Any further information will be attached if needed.

sorry, it's not a bug. some options in "barbican" section are not configured in nova.conf, like "endpoint_template". abandoned.
