Alex Schultz 7ddbe74712 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 b903446fa4 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.

Guillaume Abrioux ce86d695c2 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

`podman rm --storage <container>` before starting it.

Dimitri Savineau d408c75d76 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.

Mike Christie 76753e64f9 iscsi: Fix crashes during rolling update
During a rolling update we will run the ceph iscsigw tasks that start
the daemons then run the configure_iscsi.yml tasks which can create
iscsi objects like targets, disks, clients, etc. The problem is that
once the daemons are started they will accept confifguration requests,
or may want to update the system themself. Those operations can then
conflict with the configure_iscsi.yml tasks that setup objects and we
can end up in crashes due to the kernel being in a unsupported state.

This could also happen during creation, but is less likely due to no
objects being setup yet, so there are no watchers or users accessing the
gws yet. The fix in this patch works for both update and initial setup.

It doesn't break anything currently but it could be confusing when
using podman.

Guillaume Abrioux 9d590f4339 iscsi: fix permission denied error
Typical error:
```
fatal: [iscsi-gw0]: FAILED! =>
  msg: 'an error occurred while trying to read the file ''/home/guits/ceph-ansible/tests/functional/all_daemons/fetch/e5f4ab94-c099-4781-b592-dbd440a9d6f3/iscsi-gateway.key'': [Errno 13] Permission denied: b''/home/guits/ceph-ansible/tests/functional/all_daemons/fetch/e5f4ab94-c099-4781-b592-dbd440a9d6f3/iscsi-gateway.key'''
```

`become: True` is not needed on the following task:

`copy crt file(s) to gateway nodes`.

Since it's already set in the main playbook (site.yml/site-container.yml)

The thing is that the files get generated in the 'fetch_directory' with
root user because there is a 'delegate_to' + we run the playbook with
`become: True` (from main playbook).

The idea here is to create files under ansible user so we can open them
later to copy them on the remote machine.
