ansible log of the playbook execution

Description of problem:
-----------------------
In the non-containerized ceph cluster (RHCS 4.x) in RHEL 7.9 node-exporter service still runs as containerized. So before upgrading the OS from RHEL 7 to 8, we have to convert the container runtime from docker to podman for the node-exporter service as it is containerized.

Now, after executing the playbook and reboot the nodes one by one, I see that:
MON/MGRs = non-containerized (EXPECTED)
RGW and MDS = non-containerized (EXPECTED)
node-exporter = containerized and container enginer changed to podman (EXPECTED)
OSD = containerized (NOT EXPECTED)

Version-Release number of selected component (if applicable):
RHCS 4.3z1

How reproducible:
Always

Steps to Reproduce:
1. Install a RHCS 4.3z1 non-containerized cluster
2. Run the docker-to-podman playbook to change the container engine for the node-exporter
3. Reboot the nodes and check the `podman ps` output.

Actual results:
OSD come as containerized

Expected results:
OSD should be non-containerized
