Completely restructure the daemon code to move the 4 discrete daemons into a single daemon that can be run on every hypervisor. Introduce the idea of a static list of "coordinator" nodes which are configured at install time to run Zookeeper and FRR in router mode, and which are allowed to take on client network management duties (gateway, DHCP, DNS, etc.) while also allowing them to run VMs (i.e. no dedicated "router" nodes required).
