    install rabbitmq-server in serial

    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.

    Based on commit: 21c24789019bf1ee85347356fe6c70b0b9045d7c
