Puppet module to deploy Manila Share bundle for HA
This module is used by tripleo-heat-templates to configure and deploy Kolla-based manila-share containers managed by pacemaker. We use short-lived containers that call pcs via puppet to create the needed pacemaker resources, properties and constraints. Based on work done in fc5bc07b3be401694681420ba453af29b95a9fcf Change-Id: I89f65e8a34a3a88029498463942016a9f5285f1c Partial-Bug: #1668922
