That include was skipped because of this condition :

before managing mgr modules, we must ensure all mgr are available
otherwise we can hit failure like following:
```
stdout:Error ENOENT: all mgr daemons do not support module 'restful', pass --force to force enablement
```
It happens because all mgr are not yet available when trying to manage
with mgr modules.

We don't need to set After=docker.service when the container_binary

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.

When collocating mon and mgr, the mgr container will attempt to create

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 data structure has slightly changed on mimic.
Prior to mimic, it used to be:
```
{
"enabled_modules": [
"status"
],
"disabled_modules": [
"balancer",
"dashboard",
"influx",
"localpool",
"prometheus",
"restful",
"selftest",
"zabbix"
]
}
```
From mimic it looks like this:
```
{
"enabled_modules": [
"status"
],
"disabled_modules": [
{
"name": "balancer",
"can_run": true,
"error_string": ""
},
{
"name": "dashboard",
"can_run": true,
"error_string": ""
}
]
}
```
This means we can't simply check if `item` is in `item in
_ceph_mgr_modules.disabled_modules`
the idea here is to use filter `map(attribute='name')` to build a list
when deploying mimic.

Use a nicer syntax for `local_action` tasks.
We used to have oneliner like this:
```
local_action: wait_for port=22 host={{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }} state=started delay=10 timeout=500 }}
```
The usual syntax:
```
local_action:
module: wait_for
port: 22
host: "{{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }}"
state: started
delay: 10
timeout: 500
```
is nicer and kind of way to keep consistency regarding the whole
playbook.
This also fix a potential issue about missing quotation :
```

We generate the ceph.conf on all the nodes through the
ceph-docker-common so there is no need to push it to the Ansible file.
Also this is breaking the ceph.conf template generation since we only
generate sections based on the host the ansible task is running on.
For example, what's typically happening, we bootstrap the monitor, we
get a ceph.conf generated for a mon only, we go on an osd, we generate
the ceph.conf with osd section (done by ceph-docker-common) but this
gets overwritten by the copy_config task of the ceph-osd role.

ceph services can fail to start under certain circumstances (for
example, when running in a container) because the default systemd
service configuration causes namespace issues.
To work around this we can override the system service settings by
placing an overrides file in the ceph-<service>@.service.d directory.
This can be generic so as to allow any potential changes required to
the ceph-<service> service files.
The overrides file is only setup when the
"ceph_<service>_systemd_overrides" config_template override variable is
specified.
The available service systemd override files are as follows:
ceph_mds_systemd_overrides
ceph_mgr_systemd_overrides
ceph_mon_systemd_overrides
ceph_osd_systemd_overrides
ceph_rbd_mirror_systemd_overrides
ceph_rgw_systemd_overrides
This will give us more flexibility and avoid a lot of useless when
skipping all tasks from a non-desired role.
