Matt Kassawara a5fd95d740 Fixed AMQP configuration steps for Block Storage 
I fixed the AMQP configuration steps in cinder.conf for Block Storage
on both controller and service nodes. I also unified structure and
phrasing with other portions of the guide and mentioned replacing
'RABBIT_PASS'. This patch affects all distributions.

I also found and fixed a minor issue causing several database
configuration instructions for other distributions to leak into those
for Debian which uses Debconf.
