Stone: Introducing freedesktop.org GitLab

Daniel Stone reflectson the completion of freedesktop.org's move to a GitLab-basedinfrastructure. "We've spent the past couple of years paying downour technical debt, and the community equivalent thereof. Ourinfrastructure is much less error-prone than it was: we've gone fromfighting fires to being able to prepare the new GitLab infrastructure andspend time shepherding projects through it. Now that we have a fair fewprojects on GitLab and they've been able to serve themselves, we've beenable to take some time for community issues."
