Guillaume Abrioux 7acd9686ab osd: use default crush rule name when needed
When `rule_name` isn't set in `crush_rules` the osd pool creation will
fail.
This commit adds a new fact `ceph_osd_pool_default_crush_rule_name` with
the default crush rule name.

Guillaume Abrioux 98783a17b3 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 ae06d684b8 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`

Dimitri Savineau 4d32ecc980 Force osd pool min_size value to integer
After b8d580b and e9e5d5a we could have either item.min_size or
osd_pool_default_min_size using string instead of int causing the
condition to be true when it's false.
As a result, the task could try to set the pool min_size value to
0 which leads to:

Error EINVAL: pool min_size must be between 1 and 1

Guillaume Abrioux 7774069d45 refact osd pool size customization
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`.

When deploying a large number of OSD nodes it can be an issue because the

OSDs are active.

The idea here is to move cephfs pools creation in `ceph-mds` role.
