Log connection info returned from driver
Log connection info returned from driver

Currently there is no way to verify the connection info returned
from the driver to cinder is the same as what cinder sends to nova
(or other consumers) to connect to the volume.
This log will help narrow down issues during attachments since there
are many components involved (nova, cinder, os-brick).
