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.

This isn't backported from master because there are too many changes
between stable-3.2 and other newer branches.

NOTE:
This playbook  *doesn't* add podman support in stable-3.2 at all.
This is a tripleO dedicated playbook which is intended to be run
early during FFU workflow in order to prepare the OS upgrade.

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.

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

The name docker_version is very generic and is also used by other
roles. As a result, there may be name conflicts. To avoid this a
ceph_ prefix should be used for this fact. Since it is an internal
fact renaming is not a problem.

This will solve the following issue when starting docker containers on ubuntu:

invalid argument "1\u00a0" for --cpus=1 : failed to parse 1  as a rational number

Closes-bug: #2056

Less configuration for the user, the container inherit from the global

This can be controlled via 2 options:

* ceph_$DAEMON_docker_memory_limit
* ceph_$DAEMON_docker_cpu_limit

All daemons default to 1GB for memory and 1 CPU by default.

`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.

The Ceph Manager daemon (ceph-mgr) runs alongside monitor daemons, to
provide additional monitoring and interfaces to external monitoring and
management systems.

Only works as of the Kraken release.

Created containers now are named more or less in the form of

    <ansible role>-<ansible_hostname>

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.

This fixes #845 for containerized deployments. We now also mount the
/etc/localtime volume in the containers in order to synchronize the host
timezone with the container timezone.
