Create OpenStack pools with crush rule Add an extra variable to the openstack pools, which creates them with defined rules. This will allow to place different pools on e.g. different type of disks. This commit will also set a new default rule when defined and move the rbd pool to the new rule.

crush: create rack type buckets and build crush tree according to {{ osd_crush_location }}. Currently, we can define crush location for each host but only crush roots and crush rules are created. This commit automates other routines for a complete solution: 1) Creates rack type crush buckets defined in {{ ceph_crush_rack }} of each osd host. If it's not defined by user then a rack named 'default_rack_{{ ceph_crush_root }}' would be added and used in next steps. 2) Move rack type crush buckets defined in {{ ceph_crush_rack }} into crush roots defined in {{ ceph_crush_root }} of each osd host. 3) Move hosts defined in {{ ceph_crush_rack }} into crush roots defined in {{ ceph_crush_root }} of each osd host.

name includes and set_fact for clarity When Ansible is not run with verbose options it's difficult to see which include and/or set_fact does what. So adding a name for each clarifies. Signed-off-by: Sébastien Han <seb@redhat.com>
