RabbitMQ nodes must all be stopped prior to a major/minor version upgrade [1]. The role does this by distinguishing between the upgrader node and the rest in separate stop and start tasks. Upgrades can fail when more than one member of rabbitmq_all are not members of the cluster. This is due to a bug fixed for greenfield deployments by 21c24789019bf1ee85347356fe6c70b0b9045d7c. The same fix was not applied to upgrades because major/minor upgrades require all RabbitMQ nodes to be stopped which is incompatible with serialising the role in isolation. This change uses a play to stop all but one of the nodes, prior to running the rabbitmq_server role, and then serialises the running of the role so that one node is upgraded at a time. This minimises the downtime as much as possible while allowing the role to be applied to one node at a time. This change is related to an equivalent one [2] made to the test playbook of the role openstack-ansible-rabbitmq_server.
