Cinder client ignores protocol and port for publicURL

[Daniel Speichert]

Cinder version 1.2.1 (Kilo version packages in RDO: 1.2.1 rel 1.el7) ignores protocol and port in publicURL when making requests.

The catalog has endpoints:
- publicURL: https://someaddress:48776/v2/%(tenant_id)s
- internalURL: http://otheraddress:8776/v2/%(tenant_id)s
- adminURL: http://otheraddress:8776/v2/%(tenant_id)s

By default, cinder makes request to: http://someaddress/v2/a8643be6b41f4e35950b1cc78f39e93a/volumes/detail

When provided with "--endpoint-type internalURL" flag, cinder makes correct (according to catalog) request to:
http://otheraddress:8776/v2/a8643be6b41f4e35950b1cc78f39e93a/volumes/detail

Need to determine if this is still the case with the latest code.
