This commit changes the bind mount option for the mount point
`/var/lib/ceph` in the systemd template for mon and mgr containers. This
is needed in case of collocating mon/mgr with osds using dmcrypt
scenario.
Once mon/mgr got converted to containers, the dmcrypt layer sub mount is
still seen in `/var/lib/ceph`. For some reason it makes the
corresponding devices busy so any other container can't open/close it.
As a result, it prevents osds from starting properly.
Since it only happens on the nodes converted before the OSD play, the idea is
to bind mount `/var/lib/ceph` on mon and mgr with the `rshared` option
so once the sub mount is unmounted, it is propagated inside the
container so it doesn't see that mount point.

In case of failure, the systemd ExecStop isn't executed so the container
isn't removed. After a reboot of a failed node, the container doesn't
start because the old container is still present in created state.
We should always try to remove the container in ExecStartPre for this
situation.
A normal reboot doesn't trigger this issue and this also doesn't affect
nodes running containers via docker.

When using docker 1.13.1, the current condition:
```
{% if (container_binary == 'docker' and ceph_docker_version.split('.')[0] is version_compare('13', '>=')) or container_binary == 'podman' -%}
```
is wrong because it compares the first digit (1) whereas it should
compare the second one.
It means we always use `--cpu-quota` although documentation recommend
using `--cpus` when docker version is 1.13.1 or higher.
From the doc:
> --cpu-quota=<value> Impose a CPU CFS quota on the container. The number of
> microseconds per --cpu-period that the container is limited to before
> throttled. As such acting as the effective ceiling.
> If you use Docker 1.13 or higher, use --cpus instead.

On containerized deployment, the mon container sometimes needs to
access to the radosgw endpoint (via the radosgw-admin command). When
using TLS on the radosgw with self-signed certificates then we need to
access to the CA certification from the mon container.
The CA certificate needs to be added on the host and then the directory
will be bind mount on the container.

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.

On containerized deployment, if a mon is stopped, the socket is not
purged and can cause failure when a cluster is redeployed after the
purge playbook has been run.
Typical error:
```
fatal: [osd0]: FAILED! => {}
MSG:
'dict object' has no attribute 'osd_pool_default_pg_num'
```
the fact is not set because of this previous failure earlier:
```
ok: [mon0] => {
"changed": false,
"cmd": "docker exec ceph-mon-mon0 ceph --cluster test daemon mon.mon0 config get osd_pool_default_pg_num",
"delta": "0:00:00.217382",

}
STDERR:

the socket isn't purged, it's a leftover which is confusing the process.

The name docker_version is very generic and is also used by other
roles. As a result, there may be name conflicts. To avoid this a
ceph_ prefix should be used for this fact. Since it is an internal
fact renaming is not a problem.
If a deployer uses an interface name with a dash/hyphen in it, such
as 'br-storage' for the monitor_interface group_var, the ceph.conf.j2
template fails to find the right facts. It looks for
'ansible_br-storage' but only 'ansible_br_storage' exists.
This patch converts the interface name to underscores when the
template does the fact lookup.
The path to the fact is not correct.
In any case, we will retrieve the IP address in hostvars, the variable
is the way we get the interface name according where it has been set

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
