Dimitri Savineau 47b7c00287 podman: always remove container on start
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.

Jonathan Rosser 92288c11c5 Install python routes package as a dependancy rather than directly
This is now a dependancy of ceph-mgr so will be installed automatically
and does not need a specific task.

This change means that ceph-mgr installs correctly on Ubuntu Focal where
the python3-routes package is necessary.

Dimitri Savineau bd22f1d1ec docker: Add Requires on docker service
When using docker container engine then the systemd unit scripts only

Dimitri Savineau 2547ab601a Readd CentOS 7 with conditions
The CentOS 7 distribution could still be used be deploying ceph if
  - it's a containerized deployment
  - it's a non containerized deployment without the dashboard (due to
missing python3 libraries).

The ceph_stable_redhat_distro variable has been remove because we can
rely on the ansible_distribution_major_version fact instead.

The copr el8 repository configuration is only applied for CentOS 8.

The ceph-mgr-dashboard package is only installed when the

Guillaume Abrioux 3e262e072b containers: use --cpus instead --cpu-quota
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.

Guillaume Abrioux 8dcbcecd71 remove container_exec_cmd_mgr fact
Iterating over all monitors in order to delegate a `
{{ container_binary }}` fails when collocating mgrs with mons, because
ceph-facts reset `container_exec_cmd` to point to the first member of

The idea is to force `container_exec_cmd` to be reset in ceph-mgr.
This commit also removes the `container_exec_cmd_mgr` fact.

Matthew Vernon 9dd913cf8a UCA: Uncomment UCA variables in defaults, fix consequent breakage
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`.

Guillaume Abrioux 8c8ec63633 container: use tmpfiles.d to creates /run/ceph
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.
