(cherry picked from commit 452069cb3a)
This commit unifies the container and non-container code, which in the
meantime gives use the ability to deploy N mon container at the same
time without having to serialized the deployment. This will drastically
reduces the time needed to bootstrap the cluster.
Note, this is only possible since Nautilus because the monitors are
bootstrap the initial keys on their own once they reach quorum. In the
Nautilus version of the ceph-container mon, we stopped generating the
keys 'manually' from inside the container, for more detail see: https://github.com/ceph/ceph-container/pull/1238

Add real default value for osd pool size customization.
Ceph itself has an `osd_pool_default_size` default value to `3`.
If users don't specify a pool size in various pools definition within
ceph-ansible, we should default to `3`.
By the way, this kind of condition isn't really clear:
```
when:
- rbd_pool_size | default ("")
```
we should try to get the customized value then default to what is in
`osd_pool_default_size` (which has its default value pointing to
`ceph_osd_pool_default_size` (`3`) as well) and compare it to
`ceph_osd_pool_default_size`.

`osd_pool_default_pg_num` parameter is set in `ceph-mon`.
When using ceph-ansible with `--limit` on a specifc group of nodes, it
will fail when trying to access this variables since it wouldn't be
defined.

If you use python3 based ansible then keys() returns a dict_keys object,
not a list of keys. This breaks the installation on such a system. Using
the list filter provides a more robust solution that should work on both
python2 and python3 based ansible. You can find some more information
about the issue, here:

since `ceph-volume` introduction, there is no need to split those tasks.
Let's refact this part of the code so it's clearer.
By the way, this was breaking rolling_update.yml when `openstack_config:
true` playbook because nothing ensured OSDs were started in ceph-osd role (In
`openstack_config.yml` there is a check ensuring all OSD are UP which was
obviously failing) and resulted with OSDs on the last OSD node not started
anyway.

The playbook has various improvements:
* run ceph-validate role before doing anything
* run ceph-fetch-keys only on the first monitor of the inventory list
* set noup flag so PGs get distributed once all the new OSDs have been
added to the cluster and unset it when they are up and running

This reverts commit e84f11e99e.
This commit was giving a new failure later during the rolling_update
process. Basically, this was modifying the list of devices and started
impacting the ceph-osd itself. The modification to accomodate the
osd_auto_discovery parameter should happen outside of the ceph-osd.
Also we are trying to not play ceph-osd role during the rolling_update
process so we can speed up the upgrade.

rolling_update relies on the list of devices when performing the restart
of the OSDs. The task that is builind the devices list out of the
ansible_devices dict only runs when there are no partitions on the
drives. However during an upgrade the OSD are already configured, they
have been prepared and have partitions so this task won't run and thus
the devices list will be empty, skipping the restart during
rolling_update. We now run the same task under different requirements
when rolling_update is true and build a list when:
* osd_auto_discovery is true
* rolling_update is true
* ansible_devices exists
* no dm/lv are part of the discovery
* the device is not removable
* the device has more than 1 sector

This is a follow up on #2628.
Even with the openstack pools creation moved later in the playbook,
there is still an issue because OSDs are not all UP when trying to
create pools.
Adding a task which checks for all OSDs to be UP with a `retries/until`
condition should definitively fix this issue.

in `ceph-osd` there is no need to set `docker_exec_cmd` since the only
place where this fact is used is in `openstack_config.yml` which
delegate all docker command to a monitor node. It means we need the
`docker_exec_cmd` fact that has been set referring to `ceph-mon-*`
containers, this fact is already set earlier in `ceph-defaults`.
By the way, when collocating an OSD with a MON it fails because the container
`ceph-osd-{{ ansible_hostname }}` doesn't exist.
Removing this task will allow to collocate an OSD with a MON.

When deploying a large number of OSD nodes it can be an issue because the
