cinder (liberty) fails to retrieve volume limit in Horizon

[PshemK]

Using standard settings for cinder and horizon the default limit values are not available in horizon.

Cinder-api logs reports:

A quick look at the config files didn't reveal any of them pointing to localhost (vs the proper keystone host).

Adding the following lines to cinder.conf:

[keymgr]
encryption_auth_url = http://10.0.10.254:5000/v3

Seems to resolve the issue.
