Description

Follow-up from discussion on IRC:

Some docker labels are mutable, meaning the image a task runs in could change from restart to restart even if the rest of the task config doesn't change. This breaks assumptions that make rolling updates the safe and preferred way to deploy a new Aurora job

Add a binding helper that resolves a docker label to an immutable image identifier at create time and make it the default for the Docker helper introduced in https://reviews.apache.org/r/28920/
