User-specifiable Control Plane IP for TripleO Routed Isolated Networks

This blueprint is part of the series of blueprints covered by the bp:tripleo-routed-networks-deployment master.

In a routed network environment, it may be desired to have specific control over which nodes receive which IP addresses according to their geographic location. Eventually this may be possible using location awareness in Ironic and Neutron, but those features are still in the design phase.

Predictable placement of the control plane IP addresses is currently not possible. This will be required for some deployments, but will also allow for testing of routed networks deployments prior to a fully automated approach. The changes required will be at the role-level. The end result will be the ability to set the Control Plane IP using a map, similar to environments/ips-from-pool-all.yaml, where IP addresses are referenced according to the NodeIndex of the resource.
