Running the last portion (insert new default and add new default crush
tasks) of crush_rules.yml only on the last monitor is
wrong since ceph CLI calls usually end up on the master having the
quorum, which is by default the one with the lower IP.
So if we run the command and end up on another mon the creation will
happen on the default crush rule because the particular mon hasn't been
updated.
To fix this we remove the |last on the include and use run_once: true on
certain tasks, then we let the final two tasks run on all the monitors.

On releases after jewel the option
'osd_pool_default_crush_replicated_ruleset' does not exist anymore, it's
called osd_pool_default_crush_rule.

Instead of creating the CRUSH hierarchy with Ansible tasks using the
command module we now rely on the ceph_crush module.

One could want to add new crush rules while keeping his current default rule.
Fixed it so that it works with all rules defined as "default: false". If multiple rules are defined as default (should not be) then the last rule listed in "crush_rules" is taken as default.
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.

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.

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.
