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.

The current ganesha log directory is only present in the container
and not bind mount on the host.

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

At the moment, we bindmount the dbus socket from the host, this requires
to run the container with --privileged.
Since we now run a dedicated dbus daemon inside the same container, we
can stop running privileged nfs-ganesha containers

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.

We don't need to set After=docker.service when the container_binary
variable isn't set to docker.
It doesn't break anything currently but it could be confusing when
using podman.

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.

/var/run/ceph resides in a non persistent filesystem (tmpfs)
After a reboot, all daemons won't start because this directory will be
missing.

Useful for softwares that do data collection/monitoring like collectd.
They can connect to the socket and then retrieve information.
Even though the sockets are exposed now, I'm keeping the docker exec to
check the socket, this will allow newer version of ceph-ansible to work
with older versions.

We know bindmount with the :z option at the end of the -v command so
this will basically run the exact same command as we used to run. So to
speak:
chcon -Rt svirt_sandbox_file_t /var/lib/ceph

* DBus on host should include ganesha service file
* to allow ganesha container to respond on DBus it needs to run
in --privileged mode (ganesha folks contacted to look at this)
* ceph_nfs_include_exports_dir variable replaced with more general
ceph_nfs_dynamic_exports
`ceph-docker-common`:
At the moment there is a lot of duplicated tasks in each
`./roles/ceph-<role>/tasks/docker/main.yml` that could be refactored in
`./roles/ceph-docker-common/tasks/main.yml`.
`*_containerized_deployment` variables:
All `*_containerized_deployment` have been refactored to a single
variable `containerized_deployment`
duplicate `cephx` variables in `group_vars/* have been removed.

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

Prior to this patch we had several ways to runs containers, we could use
ansible's docker module on some distro and on containers distros we were
using systemd. We strongly believe threating containers as services with
systemd is the right approach so this patch generalizes to all the
distros. These days most of the distros are running systemd so it's fair
assumption.

Ceph has the ability to export it's filesystem via NFS using Ganesha.
Add a ceph-nfs role that will start Ganesha and export the Ceph
filesystems.
Note that, although support is going in to export RGW via NFS, this is
not working yet.
