For symmetry and ease of transition between the docker specific
jobs/roles and generic container jobs/roles it is advantageous to have
the container upload role skip pushing artifacts to the final registry
location if we are relying on the intermediate registry instead.
Update the container upload role to skip pushing to the actual registry
if the promote var is set to intermediate registry. This allows us to
avoid reshuffling all of our jobs as we migrate between the two
implementations.
