The playbook targets 'all', which is a dynamically generated ansible group that contains all hosts. This potentially targets hosts that are not managed by OSA but exist in the same inventory namespace. This now targets the OSA hosts and containers var that contains the group names this should target. Change-Id: I3bb6ad0bc81dbf8522258cce262023335eec547e
