Dimitri Savineau f2e1941ef1 ceph-osd: wait for all osds once
cf8c6a3 moves the 'wait for all osds' task from openstack_config to the
main tasks list.
But the openstack_config code was executed only on the last OSD node.
We don't need to do this check on all OSD node so we need to add set
run_once to true on that task.

This adds device class support to crush rules when using the class key

Benoît Knecht 0cb1235962 ceph-rgw: Fix custom pool size setting
RadosGW pools can be created by setting

```yaml
rgw_create_pools:
  .rgw.root:
    pg_num: 512
    size: 2
```

for instance. However, doing so would create pools of size
`osd_pool_default_size` regardless of the `size` value. This was due to
the fact that the Ansible task used

```
{{ item.size | default(osd_pool_default_size) }}
```

as the pool size value, but `item.size` is always undefined; the
correct variable is `item.value.size`.

Dimitri Savineau 43ffcd7d28 ceph-infra: open dashboard port on monitor
When there's no mgr group defined in the ansible inventory then the
mgrs are deployed implicitly on the mons nodes.
If the dashboard is enabled then we need to open the dashboard port on
the node that is running the ceph mgr process (mgr or mon).
The current code only allow to open that port on the mgr nodes when they
are present explicitly in the inventory but not implicitly.

Dimitri Savineau 3ebd71c8c2 ceph-osd: fix fs.aio-max-nr sysctl condition
[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.

Mike Christie 7fbd76c93a iscsi-gw: Fix rtslib installation
When using python3 the name of the rtslib rpm is python3-rtslib. The
packages that use rtslib already have code that detects the python
version and distro deps, so drop it from the ceph iscsi gw task list and
let the ceph-iscsi rpm dependency handle it.

Dimitri Savineau 35963194a7 rbd-mirror: fail if the peer is not added
Due the 'failed_when: false' statement present in the peer task then
the playbook continues to ran even if the peer task was failing (like
incorrect remote peer format.

"stderr": "rbd: invalid spec 'admin@cluster1'"

This patch adds a task to list the peer present and add the peer only if
it's not already added. With this we don't need the failed_when statement
anymore.

Dimitri Savineau 86b7137b27 ceph-iscsi: notify rbd target services
When the iscsi gateway or the ceph configuration file change then we
need to notify the rbd target api/gw services to be restarted.
This patch also merges the rbd-target-api and rbd-target-gw handler
into a single file and listen.
