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.

This changes the way we are running the podman containers via systemd.
They are now in dettached mode and Type/PIDFile set.

When using docker container engine then the systemd unit scripts only
use a dependency on the docker daemon via the After parameter.
But if docker is restarted on a live system then the ceph systemd units
should wait for the docker daemon to be fully restarted.

Because we are relying on docker|podman for managing containers then we
don't need systemd to manage the process (like kill).

Typical error:
```
type=AVC msg=audit(1575367499.582:3210): avc: denied { search } for pid=26680 comm="node_exporter" name="1" dev="proc" ino=11528 scontext=system_u:system_r:container_t:s0:c100,c1014 tcontext=system_u:system_r:init_t:s0 tclass=dir permissive=0
```
node_exporter needs to be run as privileged to avoid avc denied error
since it gathers lot of information on the host.

All containers are removed when systemd stops them.
There is no need to call this module in purge container playbook.
This commit also removes all docker_image task and remove all container
images in the final cleanup play.

The current port value for alertmanager, grafana, node-exporter and
prometheus is hardcoded in the roles so it's not possible to change the
port binding of those services.

069076b introduced a bug in the systemd unit script template. This
commit fixes the options used by the node-exporter container.

Instead of using the modprobe command from the path in the systemd
unit script, we can use the modprobe ansible module.
That way we don't have to manage the binary path based on the linux
distribution.

Few fixes on systemd unit templates for node_exporter and
alertmanager container parameters.
Added the ability to use a dedicated instance to deploy the
dashboard components (prometheus and grafana).
This commit also introduces the grafana_group_name variable
to refer grafana group and keep consistency with the other
groups.
During the integration with TripleO some grafana/prometheus
template variables resulted undefined. This commit adds the
ability to check if the group exist and create, accordingly,
different job groups in prometheus template.

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.

This commit aligns the way the different containers are managed with how
it's currently done with the other ceph daemon.

This adds support for podman in dashboard-related roles. It also drops
the creation of custom network for the dashboard-related roles as this
functionality works in a different way with podman.
