Dogfood CI/CD Components/Catalog

Please take a look at @dhershkovitch 's note in our weekly meeting agenda regarding CI/CD Components/Catalog

• Take a look at the slide deck
• Book mark the CI Pipeline Components documentation
• Begin brainstorming dogfooding plan. Would it be OK to dogfood in the canonical Gitlab project, or should we start with a lower profile project first?
• @dhershkovitch could you perhaps share some guidance or examples of GitLab's CI config that could benefit from the features developed in Phase 1, to help us get started?
