Bug Description

We need to deprecate commands "service rabbitmq-server stop" and "service rabbitmq-server start" because these commands don't work and broke RabbitMQ cluster. We need to use pacemaker instead and restart Rabbit MQ services with the following commands:

pcs resource disable p_rabbitmq-server
pcs resource enable p_rabbitmq-server

Steps To Reproduce:
1) Restart RabbitMQ using "service" command:
service rabbitmq-server stop
service rabbitmq-server start
2) Check RabbitMQ status in pacemaker.

Actual Result:
RabbitMQ cluster brocken and pacemaker can't start RabbitMQ on this node, because 'service rabbitmq-server start' will remove and change pid of the process.

Expected Result:
Commands 'service rabbitmq-server start' and 'service rabbitmq-server stop' are not available of controllers and it is possible to restart RabbitMQ only with pacemaker.

The issue reproduced on 7.0, 8.0 and 9.0 versions.

Hmm, how are we going to 'deprecate' those?
Should we just avoid using those commands?

There were some changes to prevent rabbitmq from starting during package installation. So 'deprecation' is a next step - we just need to remove init/upstart/systemd stuff from packages completely. The question is what we should do with Fuel master node, which also depends on rabbit. Or it's safe to assume that master node is always centos, and controllers are always trusty?

I think it will be true for 8.0-10.0 releases but it can be changed in the future.
