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`

(cherry picked from commit 5a03e0ee1c)
Since ed36a11 we move the crush rules creation code from the ceph-mon to
the ceph-osd role.
To keep the backward compatibility we kept the possibility to set the
crush variables on the mons side but we didn't move the default values.
As a result, when using crush_rule_config set to true and wanted to use
the default values for crush_rules then the crush rule ansible task
creation will fail.
"msg": "'ansible.vars.hostvars.HostVarsVars object' has no attribute
'crush_rules'"
This patch move the default crush variables from ceph-mon to ceph-osd
role but also use those default values when nothing is defined on the
mons side.

Before this patch, the lvm2 package installation was done during the

However we were running ceph-volume command in the ceph-config role
before ceph-osd. If lvm2 wasn't installed then the ceph-volume command
fails:

[1] introduced a regression on the fs.aio-max-nr sysctl value condition.
The enable key isn't a boolean but a string because the expression isn't
evaluated.
This string output "(osd_objectstore == 'bluestore')" is always true
because item.enable condition only matches non empty string. So the
sysctl value was applyied for both filestore and bluestore backend.
[2] added the bool filter to the condition but the filter always returns
false on string and the sysctl wasn't applyed at all.
This commit fixes the enable key value by evaluating the value instead
of using the string.

When creating OpenStack pools, we only check if the return code from
the pool list command isn't 0 (ie: if it doesn't exist). In that case,
the return code will be 2. That's why the next condition is rc != 0 for
the pool creation.
But in containerized deployment, the return code could be different if
there's a failure on the container engine command (like container not
running). In that case, the return code could but either 1 (docker) or
125 (podman) so we should fail at this point and not in the next tasks.

The ceph-volume lvm list command takes ages to complete when having

For instance, with 25 OSDs on a node it takes 3 mins 44s to list the

Adding the max open files limit to the container engine cli when
executing the ceph-volume command seems to improve a lot thee
execution time ~30s.
This was impacting the OSDs creation with ceph-volume (both filestore
