Use child pipelines instead of multi-project pipelines for package-and-qa runs
Now with the ability to run any type of pipelines in any mirror of the project, for MRs from omnibus-gitlab
, instead of triggering a pipeline in omnibus-gitlab-mirror
, we can just create a child pipeline. This will save us from "waiting for SHA in mirror" problems during a security release.
Note: For package-and-qa
runs from gitlab-org/gitlab
MRs, we will still use omnibus-gitlab-mirror
so as not to pollute omnibus-gitlab
pipelines page with such triggers.
