##### SUMMARY
When running ansible inside a container with podman, I get

```
"ansible_virtualization_role": "host", 
"ansible_virtualization_type": "kvm",
``` 
It does not detect that it is a guest running inside a container

        "ansible_virtualization_role": "host", 
        "ansible_virtualization_type": "kvm", 
```
inside a docker container I get

```
[root@f443309ca58b /]# ansible localhost -m setup|grep 'ansible_virtualization'```
        "ansible_virtualization_role": "guest", 
        "ansible_virtualization_type": "docker", 
```

##### EXPECTED RESULTS

```
[root@ff0affb75461 /]# ansible localhost -m setup|grep 'ansible_virtualization'
        "ansible_virtualization_role": "guest", 
        "ansible_virtualization_type": "podman", 
```

##### ACTUAL RESULTS

```paste below
[root@ff0affb75461 /]# ansible localhost -m setup|grep 'ansible_virtualization'
