Dimitri Savineau de8f2a9f83 container: move lvm2 package installation
Before this patch, the lvm2 package installation was done during the
ceph-osd role.
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:

error checking path "/run/lock/lvm": stat /run/lock/lvm: no such file or
directory

This wasn't visible before because lvm2 was automatically installed as
docker dependency but it's not the same for podman on CentOS 8.

Dimitri Savineau 5bd1cf40eb 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.

Dimitri Savineau ece46d33be 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.

Dimitri Savineau d549fffdd2 ceph-osd: check container engine rc for pools
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.

Dimitri Savineau b987534881 ceph-volume: Set max open files limit on container
The ceph-volume lvm list command takes ages to complete when having
a lot of LV devices on containerized deployment.
For instance, with 25 OSDs on a node it takes 3 mins 44s to list the
OSD.
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
and bluestore) when using multiple LV devices.

before any new osds can be created.

The existing task checks that the number of OSDs is equal to the number of up OSDs before continuing.

The problem is that if none of the OSDs have been discovered yet, the task will exit immediately and subsequent pool creation will fail (num_osds = 0, num_up_osds = 0).

This is related to Bugzilla 1578086.

In this change, we also check that at least one OSD is present. In our testing, this results in the task correctly waiting for all OSDs to come up before continuing.
