Somewhat something changed with the introduction of msg2 and we have to
add each node as a peer so the monitors can form a quorum. This might be
due to our CI environment, although adding this is completly harmless
and solves monitors not being able to form quorum.
It seems that the initial monitor map wasn't containing the right
information about the peers (addresses like 0.0.0.0/0r1, for each rank.

On containerized deployment, if a mon is stopped, the socket is not

purge playbook has been run.
Typical error:
```
fatal: [osd0]: FAILED! => {}
MSG:
'dict object' has no attribute 'osd_pool_default_pg_num'
```
the fact is not set because of this previous failure earlier:
```

On containerized deployment,
when upgrading from jewel to luminous, mgr keyring creation fails because the
command to create mgr keyring is executed on a container that is still
running jewel since the container is restarted later to run the new
image, therefore, it fails with bad entity error.
To get around this situation, we can delegate the command to create
these keyrings on the first monitor when we are running the playbook on the last monitor.
That way we ensure we will issue the command on a container that has
been well restarted with the new image.

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.

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.
Previously it was necessary to provide a value (eventually an
empty string) for the "rule_name" key for each item in
openstack_pools. This change makes that optional and defaults to
empty string when not given.
Since Luminous we need to set the application tag for each pool,
otherwise a CEPH_WARNING is generated when the pools are in use.
We should assign the OpenStack pools to their default which would be
"rbd". When updating to Luminous this would happen automatically to the
vms, images, backups and volumes pools, but for new deploys this is not
the case.
While hostname -f will always return an hostname including its
domain part and -s without the domain part, the behavior when
no arguments are given can include or not include the domain part
depending on how the system is configured; the socket name might
not match the instance name then.

Use a nicer syntax for `local_action` tasks.
We used to have oneliner like this:
```
local_action: wait_for port=22 host={{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }} state=started delay=10 timeout=500 }}
```
The usual syntax:
```
local_action:
module: wait_for
port: 22
host: "{{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }}"
state: started
delay: 10
timeout: 500
```
is nicer and kind of way to keep consistency regarding the whole
playbook.
