Dimitri Savineau 2377da8f9b infra: use dedicated variables for balancer status
The balancer status is registered during the cephadm-adopt, rolling_update
and swith2container playbooks. But it is also used in the ceph-handler role
which is included in those playbooks too.
Even if the ceph-handler tasks are skipped for rolling_update and
switch2container, the balancer_status variable is erased with the skip task
result.

play1:
  register: balancer_status
play2:
  register: balancer_status <-- skipped
play3:
  when: (balancer_status.stdout | from_json)['active'] | bool

This leads to issue like:

The conditional check '(balancer_status.stdout | from_json)['active'] | bool'
failed. The error was: Unexpected templating type error occurred on
({% if (balancer_status.stdout | from_json)['active'] | bool %} True
{% else %} False {% endif %}): expected string or buffer.

In the `set osd flags` block, run the Ceph commands that gather information

This allows the tasks that depend on the variables set by those tasks to

Dimitri Savineau fa2bb3af86 switch2container: disable ceph-osd enabled-runtime
When deploying the ceph OSD via the packages then the ceph-osd@.service
unit is configured as enabled-runtime.
This means that each ceph-osd service will inherit from that state.
The enabled-runtime systemd state doesn't survive after a reboot.
For non containerized deployment the OSD are still starting after a
reboot because there's the ceph-volume@.service and/or ceph-osd.target
units that are doing the job.

$ systemctl list-unit-files|egrep '^ceph-(volume|osd)'|column -t
ceph-osd@.service     enabled-runtime
ceph-volume@.service  enabled
ceph-osd.target       enabled

When switching to containerized deployment we are stopping/disabling
ceph-osd@XX.servive, ceph-volume and ceph.target and then removing the
systemd unit files.
But the new systemd units for containerized ceph-osd service will still
inherit from ceph-osd@.service unit file.

As a consequence, if an OSD host is rebooting after the playbook execution
then the ceph-osd service won't come back because they aren't enabled at
boot.

This patch also adds a reboot and testinfra run after running the switch
to container playbook.

The ceph status command returns a lot of information stored in variables
and/or facts which could consume resources for nothing.
When checking the pgs state, we're using the pgmap structure in the ceph

To optimize this, we could use the ceph pg stat command which contains
the same needed information.
This command returns less information (only about pgs) and is slightly
faster than the ceph status command.

Guillaume Abrioux 7dd68b9ac1 rgw: fix multi instances scaleout
When rgw and osd are collocated, the current workflow prevents from
scaling out the radosgw_num_instances parameter when rerunning the
playbook.

The environment file used in the rgw systemd template is rendered when
executing the `ceph-rgw` role but during a new run of the playbook (in
order to scale out rgw instances), handlers are triggered from `ceph-osd`
role which is run before `ceph-rgw`, therefore it tries to start the new
rgw daemon whereas its corresponding environment file hasn't been
rendered yet and fails like following:

```
ceph-radosgw@rgw.ceph4osd3.rgw1.service failed to run 'start-pre' task: No such file or directory
```

This commit moves the tasks generating this file in `ceph-config` role
so it is generated early.

Kevin Jones 47bf47c9d8 Set proper ownership command performance improvement
By changing the set ownership command from using the file module in combination with a with_items loop to a raw chown command, we can achieve a 98% performance increase here.

On a ceph cluster with a significant amount of directories and files in /var/lib/ceph, the file module has to run checks on ownership of all those directories and files to determine whether a change is needed.

In this case, we just want to explicitly set the ownership of all these directories and files to the ceph_uid

Guillaume Abrioux 55420d6253 roles: introduce `ceph-container-engine` role
This commit splits the current `ceph-container-common` role.

This introduces a new role `ceph-container-engine` which handles the
tasks specific to the installation of containers tools (docker/podman).

This is needed for the ceph-dashboard implementation for 2 main reasons:

1/ Since the ceph-dashboard stack is only containerized, we must install
everything needed to run containers even in non containerized
deployments. Splitting this role allows us to not have to call the full
`ceph-container-common` role which would run a bunch of unneeded tasks
that would have been skipped anyway.

2/ The current implementation would have required to run
`ceph-container-common` on all ceph-clients nodes which would have been
conflicting with 9d3517c670 (we don't want
to run ceph-container-common on all client nodes, see mentioned commit
for more details)

Guillaume Abrioux 4064035a54 switch_to_containers: use ceph binary from container
use the ceph binary from the container instead of the host.
If the ceph CLI version isn't compatible between host and container
image, it can cause the CLI to hang.

Guillaume Abrioux 7e0a70f7a8 switch_to_containers: do not try to redeploy monitors
`ceph-mon` tries to redeploy monitors because it assumes it was not yet
deployed since `mon_socket_stat` and `ceph_mon_container_stat` are
undefined (indeed, we stop the daemon before calling `ceph-mon` in the
switch_to_containers playbook).

Guillaume Abrioux 0eb56e36f8 introduce new role ceph-facts
sometimes we play the whole role `ceph-defaults` just to access the
default value of some variables. It means we play the `facts.yml` part
in this role while it's not desired. Splitting this role will speedup
the playbook.

Closes: #3282
