Bring cinder up-to-date with new oslo libraries

New versions of the oslo libraries have been released and
this has broken Cinder in the gate.  The first issue is
causing all unit tests to fail with the message:

"NoSuchOptError: no such option: fake_rabbit"

This was due to commit bcb3b23b8f6e7d01e38fdc031982558711bb7586
removing that option from oslo/messaging/_drivers/impl_rabbit.py .
We were trying to set that option in cinder/tests/conf_fixture.py .
I have removed that code.

Second, the update has made etc/cinder.conf.sample go out of date
again.  I am merging the changes to bring it back up to date.

This change also disables execution of check_uptodate.sh execution
from the gate.
