Previously, Packstack created many individual manifest files from
smaller snippets (templates), and executed them following a certain
order. This is sub-optimal, since it forces code duplication and goes
against the Puppet design of running a single manifest.
This patch refactors the manifest execution, following these principles:
- Only 3 templates used, so max 3 Puppet executions on a host: controller
manifest, network node manifest, compute node manifest.
- The previous snippets are now part of the Packstack Puppet module, and
included as needed by the controller/network/compute manifests. This
concept is similar to the one used by the puppet-openstack-integration
project [1].
- The remaining Python code is left untouched, so we can keep complete
compatibility with previous answer files.
- Redis HA support has been removed, as this was the only service with
HA enabled and didn't fit the general purpose of Packstack.
