Running `keepalived` as a DaemonSet will allow managing floating
"virtual" IP addresses for Kubernetes services with configured external
IP addresses. The main services we want to expose outside the cluster
are _ingress-nginx_, Mosquitto, and RabbitMQ. The `keepalived` cluster
will negotiate using the VRRF protocol to determine which node should
have each external address. Using the process tracking feature of
`keepalived`, we can steer traffic directly to the node where the target
service is running.
