RabbitMQ is an AMQP message broker. It will be used by `xactmon` to pass messages between the components. Although RabbitMQ can be deployed in a high-availability cluster, we don't really need that level of robustness for `xactmon`, so we will just run a single instance. Deploying a single-host RabbitMQ server is pretty straightforward. We're using mTLS authentication; clients need to have a certificate issued by the *RabbitMQ CA* in order to connect to the message broker. The `rabbitmq-ca` _cert-manager_ ClusterIssuer issues these certificates for in-cluster services like `xactmon`.
