WIP: Add container registry spec
What does this MR do?
Adds the first container registry related spec at the end to end level. This tests a simple scenario where an image is uploaded to the registry after being built.
Documentation for reference: https://docs.gitlab.com/ee/user/packages/container_registry/#build-and-push-by-using-gitlab-cicd
Uses the :packages
tag to tie to the scenario in GitLab that prepares an instance that has Packages & Registry enabled. The Registry omnibus setting is also in progress on a separate MR for GitLab QA.
