Fix the locally non-existent image fails with AttributeError

[milanbalazs]

The code for running a new container with an image that is not present locally tries to access the ImagesManager via self.client.images.
As self.client is an APIClient instance and not an instance of PodmanClient, an AttributeError occurs:

AttributeError: 'APIClient' object has no attribute 'images'

With this fix the PodmanClient object is used instead of APIClinet correctly.

A very minimal test code:

import podman

with podman.PodmanClient() as client:
    client.containers.run("docker.io/library/busybox:latest")

The above code failed with AttributeError before my fix. Currently it pulls the Image if it's not available in local and run the container.

Note:

• I guess the other @cached_property methods also can be extended with my solution if it's needed. I have extended only the ContainersManager with podman_client argument.

It's fix for:
#378
