The current version of pika in epel needs a newer version of rabbitmq-server
if it's running against one of those. RHOSP13 has a newer rabbitmq, and is
in fact the one we install on the rabbitmq/fedora messaging cluster.
Install it here and hopefully it will allow things to work with the new pika.
[PATCH] loopabull: add rhosp13 repo to install newer rabbitmq.
