Dimitri Savineau 3bd3dddcc2 container: set tcmalloc value by default
All ceph daemons need to have the TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES
environment variable set to 128MB by default in container setup.

Guillaume Abrioux 5f6050bed1 container/systemd: ensure /var/log/ceph exists
This adds a `ExecStartPre=-/usr/bin/mkdir -p /var/log/ceph` in all
systemd service templates for all ceph daemon.
This is specific to RHCS after a Leapp upgrade is done. Indeed, the
`/var/log/ceph` seems to be removed after the upgrade.
In order to work around this issue let's ensure the directory is present
before trying to start the containers with podman.

Alex Schultz 56aac327dd Use ansible_facts
It has come to our attention that using ansible_* vars that are
populated with INJECT_FACTS_AS_VARS=True is not very performant.  In
order to be able to support setting that to off, we need to update the
references to use ansible_facts[<thing>] instead of ansible_<thing>.

Guillaume Abrioux f5ba6d9b01 containers: modify bindmount option
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.

Guillaume Abrioux 5ba7824c55 container: force rm --storage on ExecStartPre
This is a workaround to avoid error like following:
```
Error: error creating container storage: the container name "ceph-mgr-magna022" is already in use by "4a5f674e113f837a0cc561dea5d2cd55d16ca159a647b7794ab06c4c276ef701"
```

that doesn't seem to be 100% reproducible but it shows up after a
reboot. The only workaround we came up with at the moment is to run
`podman rm --storage <container>` before starting it.

Dimitri Savineau 47b7c00287 podman: always remove container on start
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.
This behaviour was introduced by d43769d.

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 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.
