Remove the amqp table (the transport_url option doesn't exist in neutron anymore). Rename the debug table to cadf, and include the table. Change-Id: I718f50e2b9eaa5e6e4a20cf77f4d245dd6b6cc01 Closes-Bug: #1310061

<title>Configure the Oslo RPC messaging system</title>

<para>OpenStack projects use an open standard for messaging
|
|
middleware known as AMQP. This messaging middleware enables the
|
|
OpenStack services that run on multiple servers to talk to each
|
|
other. OpenStack Oslo RPC supports three implementations of AMQP:
|
|
<application>RabbitMQ</application>,
|
|
<application>Qpid</application>, and
|
|
<application>ZeroMQ</application>.</para>
