Dimitri Savineau 4e84b4beed ceph-facts: remove mds_name fact
The mds_name fact always gets the ansible_hostname value so we don't
need to have a dedicated fact for this and use the ansible_hostname fact
instead.

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.

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

But if docker is restarted on a live system then the ceph systemd units
should wait for the docker daemon to be fully restarted.

Guillaume Abrioux 47adc2bb08 osd: add pg autoscaler support
This commit adds the pg autoscaler support.

The structure for pool definition has now two additional attributes
`pg_autoscale_mode` and `target_size_ratio`, eg:

```
test:
  name: "test"
  pg_num: "{{ osd_pool_default_pg_num }}"
  pgp_num: "{{ osd_pool_default_pg_num }}"
  rule_name: "replicated_rule"
  application: "rbd"
  type: 1
  erasure_profile: ""
  expected_num_objects: ""
  size: "{{ osd_pool_default_size }}"
  min_size: "{{ osd_pool_default_min_size }}"
  pg_autoscale_mode: False
  target_size_ratio": 0.1
```

when `pg_autoscale_mode` is `True` user has to set a decent value in
`target_size_ratio`.

Given that it's a new feature, it's still disabled by default.

Guillaume Abrioux bf1f125d71 osd: refact osd pool creation
Currently, the command executed is wrong, eg:

```
  cmd:
  - podman
  - exec
  - ceph-mon-controller-0
  - ceph
  - --cluster
  - ceph
  - osd
  - pool
  - create
  - volumes
  - '32'
  - '32'
  - replicated_rule
  - '1'
  delta: '0:00:01.625525'
  end: '2020-02-27 16:41:05.232705'
  item:
```

From documentation, the osd pool creation command is :

```
ceph osd pool create {pool-name} {pg-num} [{pgp-num}] [replicated] \
     [crush-rule-name] [expected-num-objects]
ceph osd pool create {pool-name} {pg-num}  {pgp-num}   erasure \
     [erasure-code-profile] [crush-rule-name] [expected_num_objects]
```

it means we pass '1' (from item.type) as value for
`expected_num_objects` by default which is very likely not what we want.

Also, this commit modifies the default value when no `rule_name` is set
to use the existing variable `osd_pool_default_crush_rule`

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.

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.
