Separate the network configuration per flavor.

Separate the network configuration per flavor.

This change allows a different network config for each family of hosts. For
instance, the controller may have a different network configuration than a
block storage node. This change adds a declaration for each family in the
overcloud-resource-registry.yaml & overcloud-resource-registry-puppet.yaml.
