Support image_pull_policy for inner image

[mambon2]

We need a way to configure the image_pull_policy for the inner image. Can you please provide a way to do that?

@mambon2 the inner image is done via a docker pull so there isn't really a policy that can be set. What are you looking to achieve?

[mambon2]

I'm looking to "alwaysPull" a mutable tag instead of the cached image in kubernetes.

In docker looking to avoid locally cached image docker run --pull=always
