Description

Crane and Pulp don't set the 'Docker-content-digest' header [0]. Users want to make a HEAD request for a tag to find out if that tag is pointing to a new manifest. Without this header, users must download the manifest in order to learn its digest.

The first thing that I found when searching the web is a bug about Crane[1]. We need to fix this for Pulp 3.
