Enable deployment of TripleO onto a routed network with multiple subnets for overcloud nodes.
TripleO currently models only a single set of subnets for all overcloud nodes, and it is expected that all nodes will share at least one common subnet (the provisioning network, A.K.A. Control Plane).
In order to support larger scale, and to conform to common modern datacenter practices of limiting broadcast domains to a single rack or group of racks, TripleO should support deploying to nodes which span multiple routed subnets. TripleO will have to model multiple sets of subnets and assign IPs and router information differently depending on where in the network the node is wired up. This requires both the IP address management (IPAM) backend to support routed subnets, but also the PXE boot process will need to support booting across routers via DHCP proxy or relay.
The implementation of routed networks support for deployments will require changes to multiple projects, and has several dependencies. This blueprint serves as a master blueprint for keeping track of the overall implementation and the sub-blueprints that cover each part of the implementation.
