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.

+services
+========
+
+A TripleO nested stack Heat template that encapsulates generic configuration
+data to configure a specific service. 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. Each sequence is given a "step" (via hiera('step') that provides
+ information for when puppet classes should activate themselves.
+
+ Steps correlate to the following:
+
+ 1) Load Balancer configuration
+
+ 2) Core Services (Database/Rabbit/NTP/etc.)
+
+ 3) Early Openstack Service setup (Ringbuilder, etc.)
+
+ 4) General OpenStack Services
+
+ 5) Service activation (Pacemaker)
+
+ 6) Fencing (Pacemaker)
