3f1c6c0626
The common playbooks for cinder, neutron and nova have an initial facts gathering step. This patch switches from implicit gather_facts to direct use of the ansible setup module. The minimum set of facts are gathered, and an additional filtered set of facts about the target processor count is gathered. The processor count is used in many service templates to set the number or threads/processes used. This approach significantly reduces the size of the gathered facts which cannot be achieved directly with a gather_subset of '!all,min,hardware'. In addition, all uses of ansible facts are converted to ansible_facts[]. Change-Id: Id29f7344da7f71c9513d62c939ce2baead6ef451
