Configuring Podman networkBackend for Skupper

By default, Podman v4 and later use Netavark which works with Skupper. However, if you upgraded from an earlier version of Podman, you might need to configure Podman to use Netavark.

If you are using CNI, for example, if you upgrade from Podman v3, you must also install the podman-plugins package. For example, dnf install podman-plugins for RPM based distributions.

📌 NOTE
CNI will be deprecated in the future in preference of Netavark.

To install netavark on rpm based Linux, for example, RHEL8:
```
$ sudo dnf install netavark
```
Configure podman to use netavark by making sure the following lines exist in the /etc/containers/containers.conf file:
```
[network]
network_backend = "netavark"
```
Confirm that netavark is configured as the podman network backend:
```
$ podman info --format {{.Host.NetworkBackend}}
```
