The current approach is extremely complex and introduced a lot
of spaghetti code. This doesn't offer a good user experience at all.
It's time to think to another approach (dedicated playbook) and drop
the current implementation in order to clean up the code.

When monitors and rgw are collocated with multisite enabled, the
rolling_update playbook fails because during the workflow, we run some
radosgw-admin commands very early on the first mon even though this is
the monitor being upgraded, it means the container doesn't exist since
it was stopped.
This block is relevant only for scaling out rgw daemons or initial
deployment. In rolling_update workflow, it is not needed so let's skip
it.

when running docker-to-podman playbook, there's no need to call
`ceph-config` and `ceph-rgw` from the role `ceph-handler`.
It can even have side effects when coming from a baremetal cluster that
was previously migrated using the switch-to-containers playbook. Indeed
it might complain about missing .target systemd unit since they are
removed during that migration.

since `ceph-rgw` may be called from `ceph-handler` in some contexts we
should avoid rerunning it unnecessarily.

When collocating rgw with either a mon, mgr or osd, switching from
single site to a multisite rgw setup failed because of the handlers
triggered between the ansible play of the collocated daemon and the play
of the rgw. Since the multisite changes are not yet applied the handlers
fail.
The idea here is to ensure we run the multisite configuration from the
ceph-handler role before the restart happens, this way it won't complain
because of non existing multisite configuration.
(Note: this is also valid when simply changing a multisite configuration)

the `stat --printf=%n` returns something like following:
```

```
it makes the next task "check if the ceph osd socket is in-use" grep
like this:
```
ok: [osd0] => changed=false
cmd:
- grep
- -q
- /var/run/ceph/ceph-osd.2.asok/var/run/ceph/ceph-osd.5.asok
- /proc/net/unix
```
which will obviously fail because this path never exists. It makes the
OSD handler broken.
Let's use `find` module instead.

When rgw and osd are collocated, the current workflow prevents from
scaling out the radosgw_num_instances parameter when rerunning the
playbook in baremetal deployments.
When ceph-osd notifies handlers, it means rgw handlers are triggered
too. The issue with this is that they are triggered before the role
ceph-rgw is run.
In the case a scaleout operation is expected on `radosgw_num_instances`
it causes an issue because keyrings haven't been created yet so the new
instances won't start.

In non containerized deployment we check if the service is running
via the socket file presence.
This is done via the xxx_socket_stat variable that check the file
socket in the /var/run/ceph/ directory.
In some scenarios, we could have the socket file still present in
that directory but not used by any process.
That's why we have the xxx_stat variable which clean those leftovers.
The problem here is that we're set the variable for the handlers status
(like handler_mon_status) based on xxx_socket_stat instead of xxx_stat.
That means we will trigger the handlers if there's an old socket file
present on the system without any process associated.

The role contains all the handlers for Ceph services. We decided to
leave ceph-defaults role with variables and a few facts only. This is
useful when organizing the site.yml files and also adding the known
variables to infrastructure-playbooks.
