Upstream the rabbit OCF agent for a Pacemaker

Registered by Bogdan Dobrelya on 2015-10-16

Maintaining a huge and complex OCF agent for rabbimq cluster downstream became a great burden.
We want this script to attract broader auditory and developed upstream, as a part of the rabbitmq-server package.
There is no spec required as there is no impacts, just changing the place of the OCF script hosting and maintenance patches from
fuel-ha-utils package resided downstream to the rabbitmq-server upstream.

(out of scope) Besides that, community efforts are split to different OCF RA for rabbitmq, for further analysis see
https://github.com/lemenkov/pmk-rmq.md/blob/master/pmk-rmq.md . So the action number two is to merge efforts into The OCF RA, the consolidated upstream agent. The merge plan is described here http://lists.openstack.org/pipermail/openstack-dev/2016-April/091763.html
