Dimitri Savineau 5a03e0ee1c containers: add KillMode=none to systemd templates
Because we are relying on docker|podman for managing containers then we
don't need systemd to manage the process (like kill).

Guillaume Abrioux 3e262e072b containers: use --cpus instead --cpu-quota
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.

Dimitri Savineau 2b0616ecca ceph-mon: Bind mount the ca-trust directory
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.

Dimitri Savineau f49090df7e podman: Add systemd dependency on network.target
When using podman, the systemd unit scripts don't have a dependency
on the network. So we're not sure that the network is up and running
when the containers are starting.
With docker this behaviour is already handled because the systemd
unit scripts depend on docker service which is started after the
network.

Guillaume Abrioux 8c8ec63633 container: use tmpfiles.d to creates /run/ceph
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.

Guillaume Abrioux 9f54b3b4a7 mon: ensure socker is purged when mon is stopped
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",
    "end": "2018-07-09 22:25:53.155969",
    "failed_when_result": false,
    "rc": 22,
    "start": "2018-07-09 22:25:52.938587"
}

STDERR:

admin_socket: exception getting command descriptions: [Errno 111] Connection refused

MSG:

non-zero return code
```

This failure happens when the ceph-mon service is stopped, indeed, since
the socket isn't purged, it's a leftover which is confusing the process.

Andy McCrae 4671b9e74e Allow ceph service systemd overrides to be specified
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

e8187f6 does not fix the ipv6 as expected since `ansible_default_*` are
filled with the IP address carried by the network interface used by the

to the fact in `hostvars` is not the same according to ipv4 vs ipv6 case.

Sébastien Han c2f1dca823 docker: use a better method to pull images
We changed the way we declare image.
Prior to this patch we must have a "user/image:tag"
format, which is incompatible with non docker-hub registry where you
usually don't have a "user". On the docker hub a "user" is also
identified as a namespace, so for Ceph the user was "ceph".

Variables have been simplified with only:

* ceph_docker_image
* ceph_docker_image_tag

1. For docker hub images: ceph_docker_name: "ceph/daemon" will give
you the 'daemon' image of the 'ceph' user.

2. For non docker hub images: ceph_docker_name: "daemon" will simply
give you the "daemon" image.

Infrastructure playbooks have been modified as well.
The file group_vars/all.docker.yml.sample has been removed as well.
It is hard to maintain since we have to generate it manually. If
you want to configure specific variables for a specific daemon simply
edit group_vars/$DAEMON.yml
