Unicorn/Sidekiq/Shell: use tag:latest, pullPolicy:Always
Move all charts that use images from CNG to use tag:latest and pullPolicy:Always.
CNG has been moved to create containers from master
branch of GitLab EE, and will tag latest
build from the master
branch of CNG.
There is also now a nightly build (00:00 UTC) in CNG, so latest will be updated at least daily from the gitlab-ee
sources.
Closes #84 (closed)
