Override container image by using with_overrides

[jimxliu]

Motivation: Why do you think this is important?

The @task wrapped function inside the container image might not be aware of the container image fqn, since the image was not created when the task was being packaged into an image layer. So having the parent task in a separate container that knows child container image fqn, override the fqn of the child container image seems the way to go.

Goal: What should the final outcome look like, ideally?

Parent task can override child task container image at runtime using with_overrides(container_image='...').
