Public bug reported:

Description
===========
When rbd_user and rbd_secret_uuid are set in nova.conf, they overwrite
the values returned from Cinder in the connection_info object.
Therefore both ephemeral storage in Ceph, and multiple Cinder volume
Ceph backends can't be used at the same time.

Steps to reproduce
==================
* In nova.conf, set rbd_user, rbd_secret_uuid, images_rbd_pool, etc.
* Booting a VMs. SUCCESS
* Try attaching a volume from a pool with different credentials than
the ephemeral one. FAILS
* Unset rbd_user, rbd_secret_uuid
* Try attaching a volume from a pool with different credentials than
the ephemeral one. SUCCESS
* Try booting a VM. FAILS

Expected result
===============
Both ephemeral and multiple ceph backends should work at the same time.

Actual result
=============
Either ephemeral or multiple ceph backends works at the same time.
