Description of problem:
Right now, atomic version <system containers images> only print out hash version instead of application version like rpm -q their counterparts. One of the developers mentioned that system containers do not use the label metadata.

# atomic  version brew-pulp-docker01.web.prod.ext.phx2.redhat.com:8888/rhel7/etcd:latest
brew-pulp-docker01.web.prod.ext.phx2.redhat.com:8888/rhel7/etcd:latest: ba648b580c2ad25f95f9969ff21e138eb062d5c4f9ef3eb19b0461a75e96e8bf

Non-system containers work fine.

How reproducible:
always
