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.

This reverts commit bb2bbeb941.
Looks like when not passing `--pid=host` we are facing some issues when
deploying more than 2 OSDs in containerized environment.
At the moment, we are still troubleshooting this issue but we prefer to
revert this commit so it doesn't block any PR in the CI.
As soon as we have a fix; we will push a new PR to remove `--pid=host`
(a revert of revert...)

instead of using `RuntimeDirectory` parameter in systemd unit files,
let's use a systemd `tmpfiles.d` to ensure `/run/ceph`.
Explanation:
`podman` doesn't create the `/var/run/ceph` if it doesn't exist the time
where the container is run while `docker` used to create it.
In case of `switch_to_containers` scenario, `/run/ceph` gets created by
a tmpfiles.d systemd file; when switching to containers, the systemd
unit file complains because `/run/ceph` already exists
The better fix would be to ensure `/usr/lib/tmpfiles.d/ceph-common.conf`
is removed and only rely on `RuntimeDirectory` from systemd unit file parameter
but we come from a non-containerized environment which is already running,
it means `/run/ceph` is already created and when starting the unit to
start the container, systemd will still complain and we can't simply
remove the directory if daemons are collocated.

/var/run/ceph resides in a non persistent filesystem (tmpfs)
After a reboot, all daemons won't start because this directory will be

This task used to live in ceph-osd, but we need it defined here to that

(cherry picked from commit 452069cb3a)
Applying and passing the OSD_BLUESTORE/FILESTORE on the fly is wrong for
existing clusters as their config will be changed.
Typically, if an OSD was prepared with ceph-disk on filestore and we
change the default objectstore to bluestore, the activation will fail.
The flag osd_objectstore should only be used for the preparation, not
activation. The activate in this case detects the osd objecstore which
prevents failures like the one described above.

If an existing cluster runs this config, and has ceph-disk OSD, the
`expose_partitions` won't be expected by jinja since it's inside the
'old' if. We need it as part of the osd_scenario != 'lvm' condition.

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

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.

Since we do not have enough data to put valid upper bounds for the memory
usage of these daemons, do not put artificial limits by default. This will
help us avoid failures like OOM kills due to low default values.
Whenever required, these limits can be manually enforced by the user.

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
