When creating OpenStack pools, we only check if the return code from
the pool list command isn't 0 (ie: if it doesn't exist). In that case,
the return code will be 2. That's why the next condition is rc != 0 for
the pool creation.
But in containerized deployment, the return code could be different if
there's a failure on the container engine command (like container not
running). In that case, the return code could but either 1 (docker) or
125 (podman) so we should fail at this point and not in the next tasks.

(cherry picked from commit d549fffdd2)
When using containerized deployment we have to create the systemd
service unit based on a template.
The current implementation with ceph-disk is using the device name
as paramater to the systemd service and for the container name too.
$ systemctl start ceph-osd@sdb
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE NAMES
065530d0a27f ceph/daemon:latest-luminous ceph-osd-strg0-sdb
This is the only scenario (compared to non containerized or
ceph-volume based deployment) that isn't using the OSD id.
$ systemctl start ceph-osd@0
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE NAMES
d34552ec157e ceph/daemon:latest-luminous ceph-osd-0
Also if the device mapping doesn't persist to system reboot (ie sdb
might be remapped to sde) then the OSD service won't come back after
the reboot.
This patch allows to use the OSD id with the ceph-osd systemd service
but requires to activate the OSD manually with ceph-disk first in
order to affect the ID to that OSD.

The ceph-volume lvm list command takes ages to complete when having
a lot of LV devices on containerized deployment.
For instance, with 25 OSDs on a node it takes 3 mins 44s to list the
OSD.
Adding the max open files limit to the container engine cli when
executing the ceph-volume command seems to improve a lot thee
execution time ~30s.
This was impacting the OSDs creation with ceph-volume (both filestore
and bluestore) when using multiple LV devices.

(cherry picked from commit 21e5db8982)
The existing task checks that the number of OSDs is equal to the number of up OSDs before continuing.
The problem is that if none of the OSDs have been discovered yet, the task will exit immediately and subsequent pool creation will fail (num_osds = 0, num_up_osds = 0).
This is related to Bugzilla 1578086.
In this change, we also check that at least one OSD is present. In our testing, this results in the task correctly waiting for all OSDs to come up before continuing.

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`.

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

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.

The order of fs.aio-max-nr (which is hard-coded to 1048576) means that
if you set fs.aio-max-nr in os_tuning_params it will effectively be
ignored for bluestore scenarios.
To resolve this we should move the setting of fs.aio-max-nr above the
setting of os_tuning_params, in this way the operator can define the
value of fs.aio-max-nr to be something other than 1048576 if they want
to.
Additionally, we can make the sysctl settings happen in 1 task rather
than multiple.
