Until now it was not possible to install a specific container package
because it was somehow hardcoded.
This patch allows to override the container package name (docker.io
vs docker-ce) and refacts the package installation. This could be
achieve via the container_package_name variable.
Instead of using one task per distribution we can set the package and
service name in vars. This allows to have a unified package task.
Also refactorize the debian_prerequisites tasks because the content
was outdated.

but the service isn't enabled on boot.

When installing python-minimal on Ubuntu bionic, this will add the
/usr/bin/python symlink to the default python interpreter.
On bionic, this isn't python2 but python3.
$ /usr/bin/python --version
Python 3.6.7
The python docker library is only installed for python2 which causes
issues when running the purge-docker-cluster playbook. This playbook
uses the ansible docker modules and requires to have python bindings
installed on the remote host.
Without the bindings we can see python error reported by the docker
module.
msg: Failed to import docker or docker-py - No module named 'docker'.
Try `pip install docker` or `pip install docker-py` (Python 2.6)

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.

With 'podman version 1.0.0' on RHEL8 beta the 'get ceph version' and
'ceph monitor mkfs' commands fail [1] with "error configuring network
namespace for container Missing CNI default network".
When net=host is added these errors are resolved. net=host is used in
many other calls (grep -R net=host | wc -l --> 38).

- also add `--foreground` which seems to fix some issue we are facing when
using timeout with `podman`.
- use this fact in the `is ceph running already?` task.

If user sets "docker_pull_timeout: '0'" then do not use the
timeout command when running podman/docker pull. Also, use
"timeout -s KILL"; without KILL, podman on RHEL8 beta does
not timeout and deployment can hang.

Make linter happy and add more robustness to remote tasks by retrying 3
times (the default) before failing.

This removes a bit of unnecessary code, the check was always wrong
because of the condition 'not ceph_current_status.get('rc', 1) == 0'
It will never match since `Not` is used for bool and we are checking for
an rc.
Also, even though the check would work, this will be a major blocker for
a complete meltdown. If the whole platform is shutdown then nothing will
be up but files will be present, so this check is definitely wrong.
