Modify the container_push() rule to add an attribute marker_tag. The attribute will be optional.
The marker_tag attribute will take the name of a tag. This will be in addition to the tag passed in the tag attribute.

When marker_tag is specificed, the following needs to happen:

1. When pushing the image, the marker_tag is added in addition to the tag to the container image.
2. Change behavior of skip_unchaged_digest, when it is set to is true:

Current Behavior

Currently the rule checks the docker repo for a matching image given the sha of the current image. if there is a matching image present, the rule ignores pushing. Code

New Behavior

If a matching image is found in docker repo, check image tag. If image tag == marker_tag then ignore pushing, else push anyway (cause its not the latest image)

Subtasks:

• add marker_tag optional attribute
• add marker_tag while pushing
• change behavior of skip_unchaged_digest
