Doug Hellmann e39304d4ae fix pdf build 
The PDF build does not include content multiple times if the same file
is included in a toctree more than once. That means we need to
restructure the guide to handle the common parts differently. This
approach merges some of the previously split sections back together
using inline prose to indicate where minor variations apply for
different operating systems but retaining separate files for cases where
the differences are significant.

Debian Message queue

OpenStack uses a message queue to coordinate operations and status information among services. The message queue service typically runs on the controller node. OpenStack supports several message queue services including RabbitMQ, Qpid, and ZeroMQ. However, most distributions that package OpenStack support a particular message queue service. This guide implements the RabbitMQ message queue service because most distributions support it. If you prefer to implement a different message queue service, consult the documentation associated with it.

The message queue runs on the controller node.
