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 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
reboot. The only workaround we came up with at the moment is to run
`podman rm --storage <container>` before starting it.

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.

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.

Iterating over all monitors in order to delegate a `

The Ubuntu Cloud Archive-related (UCA) defaults in
roles/ceph-defaults/defaults/main.yml were commented out, which means
if you set `ceph_repository` to "uca", you get undefined variable
errors, e.g.
```
The task includes an option with an undefined variable. The error was: 'ceph_stable_repo_uca' is undefined
The error appears to have been in '/nfs/users/nfs_m/mv3/software/ceph-ansible/roles/ceph-common/tasks/installs/debian_uca_repository.yml': line 6, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: add ubuntu cloud archive repository
^ here
```
Unfortunately, uncommenting these results in some other breakage,
because further roles were written that use the fact of
`ceph_stable_release_uca` being defined as a proxy for "we're using
UCA", so try and install packages from the bionic-updates/queens
release, for example, which doesn't work. So there are a few `apt` tasks
that need modifying to not use `ceph_stable_release_uca` unless
`ceph_origin` is `repository` and `ceph_repository` is `uca`.

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.
