Adds hook to enable additional "AllNodes" config to be performed prior to applying puppet - this is useful when you need to build configuration data which requires knowledge of all nodes in a cluster, or of the entire deployment. As an example, there is a sample config template which collects the hostname and mac addresses for all nodes in the deployment then writes the data to all Controller nodes. Something similar to this may be required to enable creation of the nexus_config in https://review.openstack.org/#/c/198754/ There's also another, simpler, example which shows how you could share the output of an OS::Heat::RandomString between nodes.
