Currently, using Cinder's backup service with RBD the
backup-create operation gets stuck when logging
('use_json=True' must be set in the config file).
The oslo.log JSONFormatter gets stuck when passing an
RBDVolumeIOWrapper from os-brick. This happens via os-brick's
utils.trace() method which passes a connector containing
{'path': RBDVolumeIOWrapper}.
The oslo.log JSONFormatter format() method calls
oslo_serialization's jsonutils.to_primitive and passes in
this RBDVolumeIOWrapper object.
Therefore the to_primitive method eventually calls
RBDVolumeIOWrapper.read(). In order to fix this the current
path avoids mapping io.IOBase objects and fallback the wrapper
RBD volume object.
