Build QA image in Omnibus in the same stage as GitLab
Description
Currently, in Omnibus, we build GitLab image in one stage, and then we build QA image in another stage. This happens like this because of historical reasons when we were not pushing QA image to the registry, and we were running QA tests soon after building QA image (same job).
Now, we can build GitLab and QA images in the same stage, and just trigger QA pipeline in a next stage (even without using Omnibus), which should save us around 15 minutes on every qa-package
run.
What do you think about it @balasankarc?
