Configure ControllerServices via resource chains
This patch wires in a new for Mitaka Heat feature
that allows us to dynamically include a set of nested
stacks representing individual services via a Heat resource chain.
Follow on patches will use this interface to decompose the controller
role into isolated services.

This generally includes everything +needed to configure the service excluding the local bind ports which +are still managed in the per-node role templates directly (controller.yaml, +compute.yaml, etc.). All other (global) service settings go into +the puppet/service templates. + +Input Parameters +---------------- + +Each service may define its own input parameters and defaults. +Operators will use the parameter_defaults section of any Heat +environment to set per service parameters. + +Config Settings +--------------- + +Each service may define a config_settings output variable which returns +Hiera settings to be configured. + +Steps +----- + +Each service may define an output variable which returns a puppet manifest +snippet that will run at each of the following steps. Earlier manifests +are re-asserted when applying latter ones. + + * config_settings: Custom hiera settings for this service. + + * step_config: A puppet manifest that is used to step through the deployment + sequence.
