In order to prevent race conditions with nodes joining the cluster simultaneously when the cluster is first formed, we move the rabbitmq installation play to be 'serial: 1'. However, when the nodes are being upgraded, it cannot be done in serial so in this case we set 'serial: 0' There are some tasks/roles called in this playbook that can still be run in parallel, so we split out the rabbitmq-server install into a separate play so that we only serialise the parts that are necessary to ensure maximum efficiency.
