ceph-0 docker2podman execution

Description of problem:

During FFU 13 -> 16.1 with a director deployed Ceph with bluestore:

 CephAnsibleDisksConfig:                                                                                                                                                  
        devices:
            - '/dev/vdb'
            - '/dev/vdc'
            - '/dev/vdd'
            - '/dev/vde'
            - '/dev/vdf'
        osd_scenario: lvm
        osd_objectstore: bluestore

using ceph-ansible "ceph-ansible-3.2.46-1.el7cp.noarch", when the ceph nodes upgrade is reached and the command:

```
openstack overcloud external-upgrade run --stack qe-Cloud-0 --tags ceph_systemd -e ceph_ansible_limit=ceph-0
```

is executed, it fails looking for the disk_list undefined variable:

```
 fatal: [ceph-0]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'disk_list' is undefined"}

```

Here the ceph versions:

```
[root@controller-0 ~]# podman exec -it ceph-mon-controller-0 ceph versions
{
    "mon": {
        "ceph version 12.2.12-84.el7cp (1ce826ed564c8063ac6c876df66bd8ab31b6cc66) luminous (stable)": 3
    },
    "mgr": {
        "ceph version 12.2.12-84.el7cp (1ce826ed564c8063ac6c876df66bd8ab31b6cc66) luminous (stable)": 3 
    },
    "osd": { 
        "ceph version 12.2.12-101.el7cp (20a4945f2321019ed50c1844b413059c07304074) luminous (stable)": 15
    },
    "mds": {},
    "overall": {
        "ceph version 12.2.12-101.el7cp (20a4945f2321019ed50c1844b413059c07304074) luminous (stable)": 15,
        "ceph version 12.2.12-84.el7cp (1ce826ed564c8063ac6c876df66bd8ab31b6cc66) luminous (stable)": 6 
    }
}
```

and the container version used is:

```
undercloud-0.ctlplane.redhat.local:8787/rhceph/rhceph-3-rhel7:3-40
