Puppet module to deploy cinder-volume bundle for HA
This module is used by tripleo-heat-templates to configure and deploy Kolla-based cinder-volume containers managed by pacemaker. We use short-lived containers that call pcs via puppet to create the needed pacemaker resources, properties and constraints. Co-Authored-By: Michele Baldesari <michele@acksyn.org> Partial-Bug: #1668920 Change-Id: I95ad4dd89b47396bea672813d87de35e64c04b2d
