How to use the podman.libs.cached_property function in podman

    @cached_property
    def containers(self):
        """Manage containers model for libpod."""
        return Containers(self._client)

    @cached_property
    def pods(self):
        """Manage pods model for libpod."""
        return Pods(self._client)

    @cached_property
    def versions(self):
        """Access versions."""
        with self._client() as podman:
            vers = podman.GetVersion()

        client = '0.0.0'
        try:
            client = pkg_resources.get_distribution('podman').version
        except Exception:  # pylint: disable=broad-except
            pass
        vers['client_version'] = client
        return collections.namedtuple('Version', vers.keys())(**vers)

    @cached_property
    def images(self):

    @cached_property
    def system(self):
