Benoît Knecht bffca06837 ceph-handler: Fix check mode
When running in check mode with one or more Ceph daemons that need to be
restarted, the `tmpdirpath.path` variable that several handlers rely on is
undefined, leading to fatal errors.

This commit ensures the tasks that require `tmpdirpath.path` are skipped when
it's undefined.

Benoît Knecht 498acd7527 ceph-handler: Fix osd handler in check mode
Run the Ceph commands that only gather information (without making any changes
to the cluster) when running Ansible in check mode.

This allows the tasks that depend on the variables set by those tasks to
succeed in check mode.

Guillaume Abrioux f7166cccbf rolling_update: fix mon+rgw/multisite collocation
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

It can even have side effects when coming from a baremetal cluster that

it might complain about missing .target systemd unit since they are
removed during that migration.

Guillaume Abrioux 513c8cfe55 rgw: support switching from single-site to multisite
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)

it makes the next task "check if the ceph osd socket is in-use" grep
like this:

which will obviously fail because this path never exists. It makes the
OSD handler broken.

Guillaume Abrioux a802fa2810 rgw: fix multi instances scaleout in baremetal
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.

Dimitri Savineau 733596582d ceph-handler: set handler on xxx_stat result
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.

feature will be removed in version 2.12. Deprecation warnings can be disabled
by setting deprecation_warnings=False in ansible.cfg.
