Javier Pena 4587b9b4d3 Refactor manifest execution
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.
