When `rule_name` isn't set in `crush_rules` the osd pool creation will

This commit adds a new fact `ceph_osd_pool_default_crush_rule_name` with

Since [1] we can't use osd pool without replicas (size: 1) by default.
We now need to set the mon_allow_pool_size_one flag to true in the ceph
configuration and add the --yes-i-really-mean-it flag to the osd pool
set size cli.

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.

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`

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.

When using podman, the systemd unit scripts don't have a dependency

With docker this behaviour is already handled because the systemd

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.

Add real default value for osd pool size customization.
Ceph itself has an `osd_pool_default_size` default value to `3`.
If users don't specify a pool size in various pools definition within
ceph-ansible, we should default to `3`.
By the way, this kind of condition isn't really clear:
```
when:
- rbd_pool_size | default ("")
```
we should try to get the customized value then default to what is in
`osd_pool_default_size` (which has its default value pointing to
`ceph_osd_pool_default_size` (`3`) as well) and compare it to
`ceph_osd_pool_default_size`.
