libvirt: prefer cinder rbd auth values over nova.conf
In the case that the ceph storage backing volumes is different
from the one backing ephemeral storage in nova, the auth values
in the rbd connection_info could be different and not work if
we are using the nova.conf values for ephemeral storage.
This change makes the volume connection config code for rbd
prefer the cinder connection_info values if they exist, and
only falls back to nova config values if cinder doesn't have
anything set.

Title:
rbd credentials in nova.conf overwrite connection_info from cinder
Status in OpenStack Compute (nova):
Fix Released
Bug description:
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.
