Resolve docker tags to concrete identifiers for DockerContainerizer
Docker tags are mutable and can point to different different images
at different points in time. This makes a job launched with a Docker
image to be mutable across restarts of the job. This breaks Aurora's
guarantee of job immutability (except via job updates).
This change introduces a binding helper, that resolves docker name:tag
to a concrete registry/name@digest identifier. Identifying
docker images via a content-addressable digest is available via the
Docker Registry v2, that is a prerequisite for this feature.

> Client binding_helper to resolve docker label to a stable ID at create
> ----------------------------------------------------------------------
>
> Key: AURORA-1014
> URL: https://issues.apache.org/jira/browse/AURORA-1014
> Project: Aurora
> Issue Type: Story
> Components: Client, Packaging
> Reporter: Kevin Sweeney
> Assignee: Santhosh Kumar Shanmugham
> Fix For: 0.17.0
>
>
> 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/
